### Condition

Some customers may comment about the MIL (SERVICE ENGINE SOON) telltale being On at all times or On intermittently. Also, a diagnostic trouble code (DTC) 32 is stored in the powertrain control module (PCM) memory.

### Cause

The indicated position of the linear EGR valve pintle does not match actual EGR valve position when EGR valve is closed.

### Correction

Follow the diagnostic procedures for DTC 32 in the "1995 Electronic Engine Controls Service Manual" and repair is required. After repairs have been performed, clear PCM DTCs and install new PCM/EC calibration according to the calibration chart on the next page. (Refer to "Reprogramming EEPROM" in the "Service Stall System User Guide.")

If no trouble is found performing diagnostic procedures, clear PCM DTCs and install new PCM/EC calibration according to the calibration chart on the next page. (Refer to "Reprogramming EEPROM" in the "Service Stall System User Guide.")
