Code P036, EGR Pintle Position Out Of Range: Action
PCM turns on MIL. PCM disables EGR solenoid for entire ignition cycle. Transaxle shift adapts are maintained at current levels.
NOTE:
Test numbers refer to numbers on diagnostic chart.
- Checks if EGR pintle position feedback is within a valid range with EGR off.
- This step forces a high signal on the feedback circuit and checks for an appropriate result.
- This step removes signal from feedback circuit and checks for an appropriate result.
- Jumper voltage should read 5 volts since 5-volt reference line is jumpered to feedback line.
- With EGR off (EGR overridden to zero), EGR pintle position should read less than 50 counts.
- With EGR valve commanded to 50 percent, EGR pintle position should read 100-150 counts.
- With EGR valve on full, EGR pintle position should be greater than 200 counts.
- Code P036 snapshot parameter PD07 (EGR pintle position) can help determine the root cause even if problem cannot be reproduced. A low pintle position (less than 9 counts) recorded in the snapshot means a low feedback voltage caused the code to set. A high pintle position (greater than 250 counts) recorded in the snapshot means a high feedback voltage caused the code to set. An intermittent pintle position (9-250 counts) recorded in the snapshot means that code was set because PCM could not control the EGR solenoid either due to intermittents in the solenoid (circuits No. 435 and 741) or EGR valve is sticking.
