On a wide-band (broadband) O2 sensor, the trim resistor circuit that calibrates the pumping current is reading…
The wide-band trim resistor circuit on bank 1 sensor 1 reads high. Air-fuel feedback gain is wrong, causing of…
The wide-band trim resistor circuit on bank 2 sensor 1 is open. Air-fuel feedback for bank 2 cannot be calibra…
The pilot (pre) injection learning routine on a common-rail diesel did not complete successfully. Without lear…
The internal power-down timer of the engine controller does not run as expected. The module either stays awake…
The 5 V reference G output that the engine controller supplies to a group of sensors is open. All sensors fed …
The 5 V reference G voltage is below the expected level. Usually a short to ground or excessive load from a do…
The 5 V reference G voltage is above the expected level. Typical causes are a short to battery or an internal …
The 5 V reference G voltage is within range but unstable or offset against expected. Loose ground or marginal …
The wide-band trim resistor circuit on bank 2 sensor 1 reads low. Air-fuel feedback gain on bank 2 is wrong, c…
The wide-band trim resistor circuit on bank 2 sensor 1 reads high. Air-fuel feedback gain on bank 2 is wrong, …
The controller cannot drive the secondary fuel pump (B). Common on dual-tank trucks, GDI lift-pump systems, or…
Voltage on the second fuel pump control line is below the expected window. Usually a short to ground or a shor…
Voltage on the second fuel pump control line is above the expected window. Typical causes are a short to batte…
The ECU detects insufficient fuel flow from fuel pump A. Either the pump is worn out, the supply line is restr…
The second fuel pump runs but does not deliver expected volume or pressure. Worn pump, restricted filter, or l…
The torque feedback signal A from the transmission or other torque user is missing or invalid. The engine cont…
The torque feedback signal A is present but its value is implausible against measured engine load and speed. S…
The torque feedback signal A reads below its valid range. Either the source reports a value below physical pos…
Voltage on the malfunction indicator lamp control line is below the expected window. Usually a short to ground…
Voltage on the malfunction indicator lamp control line is above the expected window. Typical causes are a shor…
The glow plug control driver does not respond to commands within tolerance. Cold-start glow function is degrad…
The reductant (AdBlue) tank or line heater driver does not switch as expected. AdBlue may freeze in cold weath…
The first glow plug control module reports over-temperature. Sustained current draw or insufficient cooling ha…
