5.2. Common Fault Codes and Solutions

Below are examples of common fault codes that may appear in a diagnostic report and their possible causes:

B1352 (Ignition Key-in Circuit Error): Indicates a malfunction or general failure in the ignition key-in circuit. This code is often set when the PCM detects an issue with circuits active when the ignition is switched off but the key is still in the ignition.
U1262 (SCP Data Link Fault): Possible causes include a faulty Powertrain Control Module (PCM), an open or shorted PCM harness, or poor electrical connection in the PCM circuit.
C1284 (Oil Pressure Switch Error/Note): This code may be invalid if it appears without other related symptoms. It suggests a faulty oil pressure switch, an open or shorted oil pressure switch harness, or a poor electrical connection.
P0340 (CMP/Camshaft Position Sensor 'A' Circuit Malfunction): Indicates a malfunction in the camshaft position sensor circuit. This covers the entire circuit attached to the sensor, including wiring and the PCM. Replacing the sensor may not always resolve the issue.
P1000 (On-Board Diagnostic (OBD) Systems Readiness Test Incomplete): This is a manufacturer-specific code, commonly used by Ford, Jaguar, and Mazda, indicating that the engine control computer (ECC) has not completed its emission systems testing.
P0141 (HO2S/HTR12 Heater Circuit): Indicates a problem with the bank 1 sensor 2 oxygen sensor heater circuit.
P0161 (HO2S/HTR22 Heater Circuit Fault): Indicates a problem with the bank 2 sensor 2 oxygen sensor heater circuit.
