I have recently had the SES light come on and found that it was because of error 32. Does anyone know what this error is or have any good suggestions on how to fix it? I think it has something to do witht he EGR.
CODE 32
Trouble Code 32 indicates that the Exhaust Gas Recirculation (EGR) system has detected a fault. There are two types, the older integrated electronic EGR contains a voltage regulator which converts the ECM signal to provide different amounts of EGR flow by regulating the current to the solenoid. The ECM controls EGR flow with a pulse width modulated signal (turns "ON" and "OFF" many times a second) based on airflow, TPS, and RPM. This system also contains a pintle position sensor which works similar to a TPS sensor, and as EGR flow is increased, the sensor output also increases. The other type is a digital 3-level EGR used in newer engines. Code 32 will get set when:
(Integrated EGR) Coolant temperature above the specified amount, EGR should be on.
(Integrated EGR) EGR pintle position does not match duty cycle.
(Digital EGR) Failure of EGR system.
Possible causes include:
1) Faulty EGR valve-to-ECM connection
2) Plugged EGR passages and/or sticking EGR valve
3) Defective EGR valve
4) Defective ECM
Check the shop manual for details on vehicle specific EGR valve applications.
