DTC Detecting Condition:

Schematic Diagram:

Monitor Scantool Data
1. Connect scantool to Data Link Connector (DLC).
2. Ignition "ON" & engine "OFF"
3. Select "Diagnostic Trouble Codes (DTCs)" mode and monitor "DTC Status" parameter
4. Is the DTC B1624 present?

YES
a. Go to "Inspection & Repair" procedure

NO
a. Fault is intermittent caused by poor contact in the sensor's and/or ECM's connector or was repaired and ECM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Component Inspection
1. Connect scantool to Data Link Connector (DLC).
2. Ignition "ON" & engine "OFF"
3. Erase the DTC.
4. Is the DTC erased?

YES
a. Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.

NO
a. Substitute with a known-good IPM and check for proper operation. If the problem is corrected, replace IPM and then go to "Verification of Vehicle Repair" procedure.
