 Intake Manifold Pressure/Temperature Circuit
|
Circuit Description
The intake manifold pressure sensor is used by the electronic control module (ECM) to monitor the engine intake manifold pressure.
Component Location
Refer to Procedure 100-002 (Engine Diagrams) in Section F for a detailed component location view.
Shop Talk
Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM. Refer to Procedure 019-032 (ECM Calibration Code) in Section 19 in the corresponding Troubleshooting and Repair Manual for the engine being serviced.
This fault code becomes active when the intake manifold pressure exceeds the maximum pressure limit for a given engine rating.
Possible causes:
- Malfunctioning turbocharger wastegate
- Wastegate tampering
- Wrong turbocharger part
- Possible tampering of the fuel system or turbocharger system.
