When the PCM detects 3 occurrences of TCC slip between -20 and +50 RPM for 5 seconds, indicating the TCC is applied, when commanded OFF, then DTC P0742 sets. DTC P0742 is a type B DTC.
The PCM energizes the Torque Converter Clutch Solenoid Valve Assembly (TCC Sol. Valve Assy.) by creating a ground path on circuit 422. When grounded (energized), the valve stops converter signal oil from exhausting. This causes converter signal oil pressure to increase and move the TCC apply valve. The TCC Sol. Valve Assy. de-energizes when the PCM no longer provides a ground path. When de-energized, the valve will exhaust fluid and release the TCC

Solutions

Lean on Bank 2 means one side of the engine is getting less fuel or too much air. I also own a 4.0L and I work on these models for this code consistantly. Usually if you have a vacuum leak at the pcv valve hose behind the throttle body you will get a lean Bank 1 and 2.
My recommendation in these cases would be to change the PCV valve (helps with your gas milage) and the fuel filter; other than that you will have to be sure the fuel pressure is correct and there is no vacuum leaks on the driver side of the engine. I am 90 percent sure the fuel filter, pcv valve and clearing the codes will correct this issue.

ISSUE: This article is intended to aid in diagnosing DTC's P0171, P0174, P1130, P1131, P1150, P1151, P2195, or P2197 (system lean or lack of HEGO switches) when a vacuum leak is present. HEGO sensors, MAF sensors, and PCM replacements are not an effective repair when a vacuum leak is causing the above DTC's.

ACTION: Perform the following inspections/repairs when the above codes are found in memory. Procedure provides instructions on how to make comparisons of the total fuel corrections (using scan tool or equivalent) at idle and high RPM's to help determine if a vacuum leak is the root cause of the DTC's.

SERVICE PROCEDURE:
NOTE FREEZE FRAME AND ADAPTIVE FUEL VALUES (ASSOCIATED WITH "LONGFT" PID) WILL NOT BE AVAILABLE IF A KAM OR OBDII RESET WAS RECENTLY PERFORMED.

NOTE FREEZE FRAME DATA WILL INDICATE THE ENGINE AND AMBIENT CONDITIONS WHEN THE DTC WAS SET. THESE ARE IMPORTANT BECAUSE THE VACUUM LEAKS MAY OCCUR ONLY WITHIN SPECIFIC TEMPERATURE RANGES AND MUST BE DUPLICATED TO DETECT THE LEAK.

NOTE FUEL TRIMS AT IDLE ARE PARTICULARLY SENSITIVE TO VACUUM LEAKS SINCE THE UN-METERED AIR LEAKAGE FLOW IS A HIGHER PERCENTAGE OF TOTAL AIRFLOW AT IDLE THAN AT PART THROTTLE. THE BAROMETRIC PRESSURE (BP) PID IS NOT RECOMMENDED TO VIEW WHEN DIAGNOSING A VACUUM LEAK. BP IS AN INFERRED PID CALCULATED DURING HIGHER ENGINE LOADS.

looks like you need an ebcm. You can check the ground under the drivers side door attached to the frame, make sure it is clean and tight.



DTC C0241-C0254 or C041-C054
Circuit DescriptionThe ABS relay supplies battery voltage to 6 valve solenoids. The electronic brake control module (EBCM) microprocessor applies the grounds needed to activate each solenoid. The low side of each solenoid coil has a feedback circuit to the EBCM microprocessor. When a solenoid is commanded OFF, the feedback voltage is high. When a solenoid is commanded ON, the feedback voltage is low.
Conditions for Running the DTC • The ignition is ON. • The vehicle speed is greater than 6 km/h (4 mph). Conditions for Setting the DTCThe EBCM detects an internal malfunction.
Action Taken When the DTC Sets C0241, C0242, C0245, C0246, C0251, C0252, C0253, C0254If equipped, the following actions occur:
• The EBCM disables the DRP/ABS. • The ABS indicator turns ON. • The red brake warning indicator turns ON. C0243, C0244, C0247, C0248If equipped, the following actions occur:
• The EBCM disables the ABS. • The ABS indicator turns ON. Conditions for Clearing the DTCThe conditions for setting the DTC are no longer present and you use the scan tool Clear DTCs function.

GMC Truck Envoy - 2WD ' Envoy, Rainier, TrailBlazer, Ascender (VIN S/T) Service Manual ' Document ID: 1655997

DTC P1400
Diagnostic Instructions
• Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
• Review Strategy Based Diagnosis for an overview of the diagnostic approach.
• Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptor:
DTC P1400: Cold Start Emission Reduction Control System

Circuit/System Description
The catalytic converter must be warmed to efficiently reduce the emissions. The cold start strategy is to reduce the amount of time it takes to warm the catalytic converter. During a cold start, the engine idle speed is elevated and spark timing is retarded to allow the catalyst to warm quickly. This diagnostic monitors the following to build an exhaust energy model:

• Engine speed
• Spark advance
• Throttle position
• Engine airflow
• Engine coolant temperature
• Engine runtime
• Park/neutral position
• Vehicle speed

The actual model is then compared to the expected exhaust energy model.

Conditions for Running the DTC
• A cold start has been detected.
• The vehicle speed is less than 2 km/h.
• The engine is at idle with no input from the accelerator pedal.
• The airflow per cylinder is greater than 80 mg/cylinder.
• DTCs P0101, P0102, P0103, P0106, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0120, P0121, P0122, P0123, P0220, P0222, P0223, P0201, P0202, P0203, P0204, P0205, P0206, P0300, P0335, P0336, P0351, P0352, P0353, P0354, P0355, P0356, P0502, P0506, P0507, P0601, P0602, P0603, P0604, P0606, P0607, P062F, P0641, P0651, P1101, P1516, P1682, P2101, P2119, P2120, P2122, P2123, P2125, P2127, P2128, P2135, P2138, P2176, P2610 are not set.
• This DTC runs for 15 seconds within the first 70 seconds of start up. This diagnostic runs once per trip when a cold start has been determined.

Conditions for Setting the DTC
The actual exhaust energy model does not match the expected exhaust energy model.

Action Taken When the DTC Sets
• The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
• The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.

Conditions for Clearing the MIL/DTC
• The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
• A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
• A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
• Clear the MIL and the DTC with a scan tool.

Diagnostic Aids
Any loading of the engine that lowers engine RPM, such as with partial application of the clutch, during the first 70 seconds of engine run time may set this DTC.
Circuit/System Verification
Allow the engine to cool. Monitor the Cold Startup parameter. This should indicate Yes. Start and idle the engine for at least 2 minutes. DTC P1400 should run and pass.

Circuit/System Testing
• Inspect the air intake system for the following:
- If any other DTCs are set, diagnose them first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle.
- Modified, damaged, or restricted
- Dirty or deteriorating air filter element
- Crankcase ventilation system for correct operation--Refer to Crankcase Ventilation System Inspection/Description.
- Water intrusion
- Vacuum leak and other un-metered air downstream of the mass air flow (MAF) sensor
- Intake manifold leak

• Inspect the exhaust system for the following:
- Water intrusion
- Exhaust leak
- Damaged, restricted, modified or enhanced exhaust system--Refer to Symptoms - Engine Exhaust .


Hope helps; keep us updated

P1000 JAGUAR - On Board Diagnostic System Readiness Test Not Complete, this is known as the OBD2 drive cycle.


Possible causes - The vehicle is new from the factory.
- Battery or Powertrain Control Module (PCM) had recently been disconnected.
- An OBD monitor failure occurred before completion of an OBD drive cycle.
- PCM Detected Trouble Codes (DTC) have recently been cleared with a scan tool.
When is the code detected? If DTC P1000 is triggered after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles have not been cleared. P1000 JAGUAR Description The On Board Diagnostic (OBD) monitors are performed during the OBD Drive Cycle. P1000 is stored in continuous memory if any of the OBD monitors do not carry out their full diagnostic check.

Figure 72: Fuel Rail Components

Engine fuel temperature sensor which measures the pressure of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulsewidth and meter fuel to each engine combustion cylinder.

DTC 12 -
When terminals "A" and "B" have been connected, the ignition switch turned to the "ON" position with the engine not operating, the MIL (Service Engine Soon) should flash DTC 12 three times consequently. This will be the following flash sequence: "flash, pause, flash-flash, pause, flash, pause, flash-flash, pause, flash, pause, flash-flash." DTC 12 indicates that the control module diagnostic system is operating properly. If DTC 12 is not indicated, and a fault is present within the diagnostic system itself, it should be addresses by consulting the appropriate diagnostic chart in this section.

The MIL (SES) will indicate a diagnostic trouble code (DTC) three times if a DTC is present, or it will simply continue to output DTC 12. If more than one DTC has been stored in the control module memory, the DTC(s) will be displayed from the lowest to the highest with each DTC being displayed three times.



DTC 32 - Exhaust Gas Recirculation (EGR) Error
EGR open command did not change the fuel mixture when the command was given during off idle operation. EGR opening should cause the mixture to be slightly richer because of the low oxygen content of the exhaust gas. EGR position signal is also monitored to verify EGR movement.

The EGR relies on a certain amount of exhaust back pressure to work properly. Now that you have lowered the back pressure, it can't work. Have you tried a new EGR valve? You may need a service manual with an EGR diagnostic chart to make sure, but I think the duals are the problem. Plus the O2 sensor is only looking at one side of engine instead of both.

Keep in midn this procedure to Clearing Diagnostic Trouble Codes:
To clear the DTC's from memory of the control module, either to determine if the malfunction will occur again or because the repair has been completed, the Tech 1 Scan Tool should be used to clear the DTC's. If a Tech 1 Scan Tool is not available the following must be perform'd when all repairs have been completed. This will allow all DTC's to be cleared:
1. Ignition "OFF."
2. Ground diagnostic terminal "A" to "B" of DLC (Data Link Connector).
3. Ignition "ON."
4. Fully apply brake pedal.
5.Fully apply accelerator pedal.
6. Check MIL (Service Engine Soon) for DTC 12.
7. Release brake pedal.
8. Release accelerator pedal.
9. Check MIL (Service Engine Soon) for DTC 12.
10. Turn ignition "OFF."
11. Remove Jumper from DLC connector.

NOTICE: To prevent control module damage, the key must be "OFF" when disconnecting or reconnecting module power.

Good luck.
