P1132 Diagnostic Trouble Code
P1132 is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code.
It is considered generic because it applies to all makes and models of vehicles, although specific repair steps may be different depending on your car model.
Symptoms
Symptoms of a P1132 diagnostic trouble code may include:
- 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
- Faulty or damaged wiring
- Hesitation upon acceleration
- Engine surge
|
Possible Causes :
- Rarely - faulty Powertrain Control Module (PCM-programming required after replacement)
- Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7.
- Defective ECU strategies or components will prevent proper regeneration
|
Repair Processes :
With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
Use the DVOM to test resistance and continuity on all system circuits if actuator and sensor resistance levels are in compliance with manufacturer's specifications.
Process Tips
Diagnostic trouble code P1132 is not difficult to diagnose and repair. Thus, it always pays to have a qualified technician to look after your vehicle should this error code arise.
Diagnosing this code requires the engine to be in good running shape, without unmetered air entering the engine. If other codes that relates to misfiring condition, lean running or air entering the engine is present, then you must first fix those error codes before P1132.
Fortunately, P1132 is a fairly common OBD code, meaning that it applies to all makes and models of vehicles made after 1996.
