DIAGNOSTIC PROCEDURE
NOTE: Refer to VERIFICATION TESTS for appropriate verification test procedures.
-
Turn the ignition on. With the DRBIII®, read the Engine DTC's. Are there any other MAP Sensor related DTC's.
Yes --> Repair other MAP Sensor DTC's. Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
No --> Go To 2 -
Start the engine. With the DRBIII®, read the MAP Sensor voltage. Is the pressure reading of the MAP sensor less than 35.85 in Hg?
Yes --> Go To 3
No --> Replace the MAP Sensor. Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL). -
Operate the engine under normal driving conditions (no load) for at least 30 seconds. Monitor the MAP sensor reading with the DRBIII®. Did the pressure reading from the MAP sensor go above 22.5 in Hg for more than 2.5 seconds?
Yes --> Replace the Map sensor. Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
No --> Refer to the SYMPTOM: INTERMITTENT CONDITION. Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
