Symptoms
Symptoms of a C0144 Turner Climax diagnostic trouble code may include:
- Possible spark knock (detonation / pre-ignition)
- Poor fuel economy
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.

Possible Causes :
- Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors.
- Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors.
- Defective ECU strategies or components will prevent proper regeneration

Common Misdiagnoses
- Vehicle Speed Output Circuit Problem
- Cruise Control Servo Indicates Low Problem
- A/C System High Pressure High Temperature Problem
- PCM Stack Overrun Problem
- Transmission Control Module Reprogrammable Memory Problem
Repair Processes :
Look for damage to the tank indicating impact that may have damaged the fuel pump or sender.
Replace the oxygen sensor that is downstream from the catalytic converter on the side of the engine that does not contain cylinder #1. Also, if a oxygen sensor code stating "heater circuit malfunction" the sensor has most probably failed.
You might continue by connecting the scanner to the vehicle diagnostic connector and retrieving all stored codes and freeze frame data.
