| 41 | Fuel pump high voltage | Fuel pump is receiving voltage when the ECM is not sending the signal to the fuel pump to turn ON | Test the fuel pump relay, see the Repair Section OR check for poor terminal connections from the fuel pump relay to fuel pump OR replace the ECM. |
| 42 | Heated Oxygen (HO2) sensor high voltage | A leaking or malfunctioning fuel injector, misfiring cylinder, faulty TP sensor or contamination from fuel OR use of improper thread sealant on sensor threads OR sensor wires shorted to ground or poor terminal connections OR HO2 sensor is bad | Test for a leaking or malfunctioning fuel injector, misfiring cylinder or bad TP sensor. Remove HO2 sensor and check condition of sensor for contamination OR check for poor terminal connections or shorted wires from the HO2 sensor to the ECM to ground OR replace HO2 sensor. |
| 43 | Engine Coolant Temperature (ECT) sensor low voltage | ECM detects a excessively low signal voltage from the ECT sensor | Check engine coolant level OR check for shorted wires or poor terminal connections from the ECT sensor to the ECM OR replace the ECT sensor. |
| 45 | Intake Air Temperature (IAT) sensor low voltage | ECM detects a excessively low signal voltage from the IAT sensor. The IAT sensor shares the same ground wire as the ECT and MAP sensors. | Check for shorted wires or poor terminal connections from the IAT sensor to the ECT and MAP sensors to the ECM OR replace the IAT sensor. |
| 51 | Low oil pressure | Bad oil pressure switch, wires shorted to ground or not enough engine oil | Check engine oil level OR check for shorted wires or poor terminal connections from the oil pressure switch to the ECM OR replace the oil pressure switch. |
| 52 | Crankshaft Position (CKP) sensor senses extra or missing pulses | The CKP and CMP sensors work together; if one is bad, the other one won't work correctly and causes the ECM to detect a fault. The ECM uses the signal pulses from the CKP and CMP sensors to initiate sequential fuel injection. | Check for shorted wires or poor terminal connections from the CKP and CMP sensors to the ECM OR replace the CKP or CMP sensor. |
| 53 | Camshaft Position (CMP) sensor senses unknown pattern | The CMP and CKP sensors work together; if one is bad, the other one won't work correctly and causes the ECM to detect a fault. The ECM uses the signal pulses from the CKP and CMP sensors to initiate sequential fuel injection. | Check for shorted wires or poor terminal connections from the CKP and CMP sensors to the ECM OR replace the CKP or CMP sensor. |
| 54 | ECM Fault - Illegal Operation | The ECM received an illegal instruction signal from one or more of the sensors and has gone into a default program and then return to normal operation. | Replace the ECM. |
| 55 | ECM - Illegal Interuption | The ECM received an illegal interruption signal from one or more engine sensors and has gone into a default program and then return to normal operation. | Replace the ECM. |
| 56 | ECM - Computer Operating Properly (COP) failure | Under normal operation the ECM will store numbers into memory. If this does not happen, it will reset itself and set fault code 56. | Replace the ECM. |
| 61 | System voltage low | Battery supply voltage to the ECM is 8V DC or less | Check battery and/or alternator condition OR check for shorted wires or poor terminal connections from the battery to the ECM. |
| 62 | System voltage high | Battery supply voltage to the ECM is 18V DC or more | Check battery and/or alternator condition OR check for shorted wires or poor terminal connections from the battery to the ECM. |
