P1495 Dodge P1495 Dodge - EVAP Leak Detection Pump Solenoid Circuit Condition 3 ' Add Comment Possible causes
- Faulty Leak Detection Pump (LDP)
- Leak Detection Pump (LDP) harness is open or shorted
- Leak Detection Pump (LDP) poor electrical connection
What does this mean? When is the code detected?
Malfunction is detected when the Powertrain Control Module (PCM) detected the pump solenoid did not change status when activated,
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors
P1495 Dodge Description
The Evaporative emissions system is design to prevent the escape of fuel vapors from the fuel system. Leaks in the system, ca allow vapors to escape into the atmosphere. The leak detection system tests for EVAP system leaks and blockage.
During the self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

SOURCE: Check Engine Light code on dodge caravan ec P1495

the leak detection pump pressurizes the evaporative system to check for leaks. the computer has detected there is a fault somewhere in the cicuit (wiring) that operates the pump.

DTC P1495 - Leak Detection Pump Solenoid Circuit

WHEN MONITORED: Immediately after a cold start, with battery/ambient temperature between 4.4 °C (40 °F) . F and 32 °C (90 °F) . Coolant temperature within -12 °C (10 °F) of battery/ambient

SET CONDITION: The state of the solenoid circuit does not match the PCM's desired state.

POSSIBLE CAUSES:
* Wiring Harness Intermittent
* Leak Detection Pump
* Fused Ignition Switch Output
* LDP Solenoid Control Circuit Shorted To Ground
* LDP Solenoid Control Circuit Open
* PCM

Leak Detection Pump System
The evaporative emission system is designed to prevent the escape of fuel vapors from the fuel system. Leaks in the system, even small ones, can allow fuel vapors to escape into the atmosphere. Government regulations require on-board testing to make sure that the evaporative (EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and blockage. It also performs self-diagnostics. During self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

SYMPTOM: P1490-LOW SPEED FAN CONTROL RELAY CIRCUIT
WHEN MONITORED: With the ignition ON. Battery voltage greater than 10 volts .

SET CONDITION: An open or shorted circuit is detected in the radiator fan relay control circuit.

POSSIBLE CAUSES:
* Low Speed Radiator Fan Relay Intermittent Operation
* Intermittent Condition
* Fused Ignition Switch Output Circuit
* Low Speed Radiator Fan Relay Resistance
* Low Speed Radiator Fan Relay Control Circuit Open
* Low Speed Radiator Fan Relay Control Circuit Short To Ground
* PCM


Notes
The Transmission/Transaxle Controller monitors the malfunction of sensors and actuators relating to Transmission/Transaxle Control. If any malfunction is detected, they inform the PCM by sending a signal - By illuminating the MIL and by setting the P0700 code.

P0700 means that a code has been set in the Transmission/Transaxle Controller. If P0700 is present, check for Transmission/Transaxle codes.

Hope helps (remember comment and rated this).

06 Cadillac STS V8 car has codes P0174 and P0420.


• DTC P0171 Fuel Trim System Lean Bank 1
• DTC P0174 Fuel Trim System Lean Bank 2
.
The engine control module (ECM) controls the air/fuel metering system in order to provide the best possible combination of driveability, fuel economy, and emission control. Fuel delivery is controlled differently during Open and Closed Loop. During Open Loop, the ECM determines fuel delivery based on sensor signals without oxygen sensor (O2S) input. During Closed Loop, the O2S inputs are added and used by the ECM to calculate short and long term fuel trim (FT) fuel delivery adjustments. If the O2S indicates a lean condition, FT values will be above 0 percent. If the O2S indicate a rich condition, FT values will be below 0 percent. Short term FT values change rapidly in response to the heated oxygen sensor (HO2S) voltage signals. Long term FT makes coarse adjustments in order to maintain an air/fuel ratio of 14.7:1. If the ECM detects an excessively lean condition, DTC P0171 or P0174 sets.
Diagnostic Aids
• Excessive resistance in the fuel injector ignition 1 voltage circuit or the fuel injector control circuit may cause the following symptoms:
- Lean condition
- Misfire
- Rough idle
• The system will go lean if an injector is not suppling enough fuel.
• A lean condition could be present during high fuel demand.
• A malfunctioning MAF sensor can cause this DTC to set. Refer to DTC P0101 .
• Review the Failure Records with a scan. If an intermittent condition is suspected, refer to Intermittent Conditions .

DTC Descriptors
This diagnostic procedure supports the following DTCs:
• DTC P0420 Catalyst System Low Efficiency Bank 1
• DTC P0430 Catalyst System Low Efficiency Bank 2

This code could mean the catalytic converter on that bank has failed .

Causes of lean condition trouble codes P0171 P0174 GM 5 3L

Check engine light


P1495 indicates a Leak Detection Pump Solenoid Circuit error. The Leak Detection system is located under the hood on the driver's side inner fender. The solenoid is located under or behind the leak detection pump. This system works in conjunction with the EVAP system, and one of the most common error causes is a loose or non-airtight gas cap. Try tightening or replacing your gas cap and see if the code disappears after a normal driving cycle (about 50 miles). Good luck.

P1495 on 2000 dodge stratus 2.4 l engine how to fix the problem


The code is telling you that you have a problem with the pump.

DTC P1495 - LEAK DETECTION PUMP SOLENOID CIRCUIT
WHEN MONITORED Ignition on and battery voltage greater than 10.4 volts .
SET CONDITION The state of the solenoid circuit does not change.
POSSIBLE CAUSES Fused ignition switch output circuit open
Leak detection pump defective LDP solenoid circuit wiring harness observable def LDP solenoid ckt wiring harness intermittent def LDP solenoid control circuit short to ground Leak detection pump solenoid control circuit open Powertrain control module defective

During evaporative system diagnosis, Leak Detection Pumps have mistakenly been replaced. A thorough inspection for pinched, kinked, or disconnected supply vacuum lines (as currently listed in the Powertrain Diagnostic Procedures) is a critical step in diagnosing DTC P1494 (LDP SW OR MECHANICAL FAULT). Additionally, the other evaporative leak faults (DTC P0442 - SMALL LEAK, P0455 - LARGE LEAK, and P0456 - VERY SMALL LEAK) should have the supply vacuum lines examined for pinches or kinks prior to any LDP component replacement.



The supply vacuum lines should be checked from the engine compartment all the way to the fuel tank, including the LDP and purge system.

NOTE: VERIFY ALL RELATED SUPPLY VACUUM LINE ROUTINGS FOR PINCHES, KINKS, OR DISCONNECTION'S BEFORE REPLACING LDP SYSTEM COMPONENTS.




Hope this helps, also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Check your connections on your leak detection pump and vacuum hose to the engine. You will need a scanner to do a wiggle test on the wiring harness this is a common problem.

The code is telling you that you have a problem with the pump.

I have a 1999 mitsubishi eclipse with the stock 420a (non-turbo) engine. The check engine light turner on with two codes, p1494 and p1495. I fixed p1294 but still have no clue what p1495 is or how to fix...


I kept getting this code on my 2001 stratus it had the 3.0. The problem for me was my egr valve. I was able to clean mine with card cleaner and it worked for me. But every six months it came back and had to clean it again. Later found out I had some vacuum leaks which were causing car to run rich as cause more junk to clog egr. After fixing those the problem stopped. Good luck.
