C203D Trouble Code

View C203D obd/2 error code description and symptoms. C203D engine photo

The Transmission Fluid Pressure Switch allows the engine's control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving. If the PCM or TCM detects an issue with the hydraulic clutch or the pressure switch, the PCM or TCM will set code C203D

As long as the throttle plate remains closed, the idling speed and quality is controlled by the PCM via the idle control valve, and as can be seen from the above it should be clear that idle control on a gasoline engine is a complex affair. For instance, if the engine is started in sub-zero temperatures, the PCM will command the idling control valve to allow less air to enter the engine to enrich the air/fuel mixture to create a condition which is roughly analogous to how chokes worked on carburetted engines to control idling in cold weather.

C203D Error Code Repair Process :

For input/turbine speed sensor circuit range/performance check engine light is perhaps the most troubling of lights because it could mean so many different things, from you didn't screw the gas cap on tightly enough to look out for pistons flying through the hood and into the stratosphere. The easiest way to find out what this light is telling you is to hook your vehicle up to a scan tool. C203D error code diagnostic tool looks a little like an oversized calculator and plugs into a communication port inside the car. After you instruct it to perform the scan, it speaks input/turbine speed sensor circuit range/performance with your car's computers to find out exactly what's prompting the light to turn on.

C203D is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.

Common Causes of C203D

A common cause of code C203D is the failure of Input/Turbine Speed Sensor Circuit Range/Performance, but there are several other possible causes as well, such as ;

Continuous oil flow to the VCT piston chamber
Damaged VCT phaser
Faulty TCM or TCM programming
Oil flow restriction in the oil passages or the VCT valve body
