I have a p0107, p0112, and p1296 code. I replaced all three sensors and pcm. still all three codes

Clean Idle control valve on throttle body

The MAP sensor voltage is too low. The PCM regulates this voltage, but a short to ground or MAP sensor failure could bring this voltage down. So you need to check the wire bundle for chaving against some metal part. Known is a stud on the aft side of the head where a wire bundle passes.

Trouble Code: P0128

Thermostat Range/Performance

Trouble Code Conditions: DTC P0107, P0108, P0112, P0113, P0116-118, P0335, P0336, P0300-P0306, P0401, P0505, P1106-P1108, P1259 and P1519, engine running at road load for 10 minutes, and the PCM detected the ECT sensor input did not reach the correct closed loop value. Note: It is possible for this code to set if the engine is left running while the hood is open for an extended period in a warm climate.

Possible Causes:


Inspect for low coolant level or for an incorrect coolant mixtureCheck the operation of the thermostat (it may be stuck open)TSB 01-064 (9/11/01) contains a repair procedure for this code

What does that mean?

The Manifold Absolute Pressure (MAP) sensor responds to changes in the intake manifold pressure (vacuum). 5 Volts is supplied to the sensor from the PCM (powertrain control module). Inside the MAP sensor is a resistor that moves in relation to manifold pressure. The resistor varies the voltage between about 1 volt to 4.5 volts (depending on engine load) and that voltage signal is returned to the PCM to indicate manifold pressure (vacuum). This signal is essential for the PCM to determine fuel delivery. A P0107 DTC is set when the PCM sees that the MAP signal voltage is less than .25 volts which is too low.

Anytime the MAP sensor signal is low the vehicle will likely have a very difficult time starting. Other symptoms may include:

• Hard to start
• Long cranking times
• Sputtering/missing
• Blowing black smoke
• Poor fuel economy
• Dies intermittently
• MIL(Malfunction Indicator Lamp) illumination

Causes

The causes of a low MAP sensor signal circuit (P0107) could be any of the following:

• Bad MAP sensor
• Open or short in the signal circuit
• Open or short in the 5 Volt reference circuit
• Ground circuit open or shorted
• Bad PCM

P0107 -- CONTINUOUS
Continuous diagnostic trouble code P0107 indicated barometric pressure out of range low was detected during normal operation.

Possible cause - faulty internal BARO sensor (PCM)

Perform KOEO On-Demand Self Test. Is P0107 present?
Yes, REPLACE PCM. CLEAR DTC and RETEST.
No, P0107 is intermittent fault. CLEAR DTC. If DTC reappears, REPLACE PCM.

If you keep getting it, a new PCM is the only fix.

P1442 usually gas cap. P1449 usually vent solenoid. P1441 usually always a faulty FTP sensor. Very problematic to Malibu, Grand Am Cavaliers and Aleros. That would be my first area to check. They are also known for poor wiring connections at the Left rear passthru connector to the fuel tank and vent solenoid, but not necessarily for that code.

CODE P1296 - 5 VOLT VREF SUPPLY NOT PRESENT - POSSIBLE CAUSE MAP SENSOR VREF CIRCUIT OPEN BETWEEN THE SENSOR AND PCM / MAP SENSOR GROUND CIRCUIT OPEN BETWEEN THE SENSOR AND PCM / MAP SENSOR IS DAMAGED OR HAS FAILED / PCM HAS FAILED.

Your CODE P1276 refer to the Acelerator Pedal Position, Sensor 1 Circuit Range Performance.

Probable cause: Wiring, APP or ECM

I also found this... though its for Trailblazers... but may give you a clue:
Reduced Engine Power Message and/or Check Engine Light with any Combination of the following DTCs: P0107 P0112 P0122 P0452 P1120 P1220 P1221 P1271 P1275 P1280 P1481 P1515 P1540 P1633 P1635 P1639 P1682 #PIP3192 - (Oct 18, 2004)

Reduced Engine Power Message and/or Check Engine Light with any Combination of the Following DTCs: P0107 P0112 P0122 P0452 P1120 P1220 P1221 P1271 P1275 P1280 P1481 P1515 P1540 P1633 P1635 P1639 P1682 PCM Repeat.

The following diagnosis might be helpful if the vehicle exhibits the symptom described in the PI.

Condition/Concern:
Reduced engine power message and/or check engine light with any combination of the following DTCs: P0107 P0112 P0122 P0452 P1120 P1220 P1221 P1271 P1275 P1280 P1481 P1515 P1540 P1633 P1635 P1639 P1682

Recommendation/Instructions:
If the SI diagnostics did not isolate a concern, the following information may be helpful:
- Inspect the main engine wiring harness between the PCM and the generator assembly for a potential short to ground. There is a metal wiring harness retainer in this area that secures the main engine harness. If the harness conduit is mispositioned, some of the wiring may become exposed and chaff on the harness retainer. This may eventually cause the exposed circuit to short to ground.

- Inspect the 3 harnesses that connect to the PCM for potential shorts to ground on the metal PCM mounting bracket, just below the PCM. There are plastic harness retainers on the PCM bracket that secure the harnesses to the PCM bracket. If the harness conduit is mispositioned, some of the wiring may become exposed and chaff on the PCM bracket. This may eventually cause the exposed circuit to short to ground.

- If a chaffed circuit is found in either of the above locations, repair the circuit using the necessary SI procedures. Once the circuit is repaired, tape the area of the affected area of the harness to prevent the wires from becoming exposed in the future and secure the harness using the original harness retainer.

This applies to 04:
- 4.2L 5.3L LL8 LM4 Engine with DTC - P2120 or P2122 or P2123 or P2125 or P2127 or P2128 - kw low MIL pedal power reduced #PI01746 - (Feb 17, 2004)
- 4.2L 5.3L LL8 LM4 Engine with DTC - P2120 or P2122 or P2123 or P2125 or P2127 or P2128.

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Condition/Concern:
MIL light on. Reduced Power message on DIC. Possibles DTCs P2120 and/or P2122, P2123, P2127, and P2128.

Recommendation/Instructions:
The APP harness is clipped to the accelerator pedal bracket. The harness may chaff on the upper portion of the accelerator pedal causing a short to ground. Verify the harness is not chaffing on the accelerator pedal. After repairing the short, reposition the harness to ensure no contact between the harness and the accelerator pedal.

Hope helpes.

Hope this helps,

Trouble Code Conditions:
DTC P0107, P0108, P0112, P0113, P0117, P0118, P0121-P0123, P0125, P0440, P0442, P0443, P0446, P0449, P0452, P0453, P1106, P1107, P1111, P1112, P1114, P1115, P1121 and P1122 not set, engine started, vehicle speed less than 75 mph, system voltage over 10.0v, ECT and IAT sensors from 39-86ºF and within 16ºF at startup, BARO sensor over 75 kPa, fuel level from 15-85%, PCM detected a continuous open purge flow condition with the fuel tank pressure decreasing to less than -11" H2O during the test. The PCM seals the EVAP system by commanding the EVAP Purge valve "off" and the EVAP Canister Vent valve "on". The PCM monitors the fuel tank pressure (FTP) sensor to detect if a vacuum is being drawn on the EVAP system. If vacuum in the EVAP system is more than a set value for a certain time, this code is set.

Possible Causes:

• An improperly installed or damaged EVAP canister purge valve
  
• A temporary blockage in the EVAP canister purge valve, purge pipe, or EVAP canister could cause an intermittent condition
  
• FTP sensor is out-of-calibration, damaged or "skewed"
  
• Purge solenoid valve is damaged or has failed
  
• PCM has failed
