Symptoms
Symptoms of a P145B Lea-francis Lynx diagnostic trouble code may include:
- Vacuum leak on the engine
- Reduction in engine performance, especially at low RPM levels
- Engine surge
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
|
Possible Causes :
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.
- Faulty IMRC actuator/sensor
- Rarely - faulty Powertrain Control Module (PCM-programming required after replacement)
|
Common Misdiagnoses
- Vehicle Speed Output Circuit Problem
- Cruise Control Servo Indicates Low Problem
- A/C System High Pressure High Temperature Problem
- PCM Stack Overrun Problem
- Transmission Control Module Reprogrammable Memory Problem
Repair Processes :
If all testing has passed so far yet you still have the same code, check your scan tool and see if it can open and close the IMRC valve.
Find out what kind of system you have and verify that voltage to the fuel level sensor is present at the fuel pump wiring harness.
