U2912 Saturn Lw OBD Code

OBD/2 U2912 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 U2912

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code U2912, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code U2912 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

U2912 Saturn Lw Error Code Repair Process :

If your vehicle failed a U2912 test and the U2912 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses fuel rail pressure sensor circuit malfunction a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look fuel rail pressure sensor circuit malfunction: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Saturn Lw U2912 OBD2 Code

A common cause of code U2912 is the failure of Fuel Rail Pressure Sensor Circuit Malfunction, but there are several other possible causes as well, such as ;

• Continuous oil flow to the VCT piston chamber
• Exhaust tube
• EVAP system hose leaking
• Oil Control Valve (OCV) circuit is open or shorted

U2912 is a kind of Network Trouble Code U-code indicates that engine communication errors and shows lost communication with engine parts.U-Codes are fairly straight forward, given all of the articles and technical publications that have been written regarding these problematic codes. In most cases, it just comes down to identifying the module that isn't communicating with the other modules on the CAN bus line for whatever reason.
