Code 32 - EGR Loop Error
Under normal operating conditions, the ECM compares EGR duty cycle signal with absolute pressure signal indicated by MAP sensor. If MAP sensor signal is different from that calculated by the ECM (based on EGR duty cycle) for 10 seconds or more, a Code 32 will set and the ECM will shut down EGR.
NOTE:
The following step numbers refer to the numbers in the accompanying flow chart(s).
- Checks to determine if Code 32 can reset.
- If Diagnostic Circuit Check indicated Code 32, there is probably a minor vacuum leak in the vacuum circuit.
