TM 10-3930-675-20-1 0018 00-2 ENGINE POSITION SENSOR CIRCUITS TROUBLESHOOTING - CONTINUED 0018 00 Table 1. Error Code 1115 - Engine Position Sensor Circuit Failure Troubleshooting Procedures - Continued. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 1115 - Engine Position Sensor Circuit Failure - Continued b. Measure resistance from engine position sensor connector pin B to engine block ground. Resistance should be greater than 100k ohms. 5. Inspect engine position sensor for damage, including metal debris on end of sensor, damage to end of sensor caused by camshaft gear or flywheel ring gear, oil leakage or insulation problems such as swelling, and damaged electrical potting in sensing end of sensor. Replace damaged engine position sensor (WP 0093 00). 6. Check resistance of engine position sensor: If resistance is not as specified, replace engine position sensor (WP 0093 00). a. Measure resistance from pin A to pin D of engine position sensor. Resistance should be 1000-2000 ohms. b. Measure resistance from pin B to pin C of engine position sensor. Resistance should be 1000-2000 ohms. 7. Check for a short circuit between coils by measuring resistance from pin A to pin B of engine position sensor. Resistance should be greater than 100k ohms. If resistance is not as specified, replace engine position sensor (WP 0093 00). 8. Disconnect sensor harness from engine ECU (794). 9. Inspect engine harness and engine ECU connectors for dirty, corroded, bent, broken, and pushed back or extended pins. Clean and repair connector(s) as required (WP 0111 00).
