U2374 Trouble Code

View U2374 obd/2 error code description and symptoms. U2374 engine photo

The Throttle Position sensor signals the Engine Control Module as to the current position of the engine throttle valve.
The current throttle valve opening is based on the driver's input from the gas pedal. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.

Circuit High Input codes like U2374 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

U2374 Error Code Repair Process :

If your motor # 1 input circuit 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 U2374 and engine control unit are in charge of monitoring a bunch of different motor # 1 input circuit failure, and if they get a reading that's a little out of whack, up pops the check engine light.

U2374 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.

Common Causes of U2374

A common cause of code U2374 is the failure of Motor # 1 Input Circuit Failure, but there are several other possible causes as well, such as ;

Damaged ECM
Continuous oil flow to the VCT piston chamber
Continuous oil flow to the VCT piston chamber
Variable Camshaft Timing solenoid stuck open
