C2251 Volkswagen Saveiro OBD Code

OBD/2 C2251 error code description and symptoms.

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 C2251

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.

If your catalyst temperature sensor failure check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system C2251 and engine control unit are in charge of monitoring a bunch of different catalyst temperature sensor failure, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Volkswagen Saveiro C2251 OBD2 Code

A common cause of code C2251 is the failure of Catalyst Temperature Sensor Failure, but there are several other possible causes as well, such as ;

Continuous oil flow to the VCT piston chamber
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Incorrect Positive Crankcase Ventilation (PCV) hose connection
Camshaft advance mechanism binding (VCT unit)

C2251 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.
