U3769 Trouble Code

View U3769 obd/2 error code description and symptoms. U3769 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 U3769 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.

U3769 Error Code Repair Process :

If your trs circuit intermittent malfunction 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 U3769 and engine control unit are in charge of monitoring a bunch of different trs circuit intermittent malfunction, and if they get a reading that's a little out of whack, up pops the check engine light.

U3769 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 U3769

A common cause of code U3769 is the failure of TRS Circuit Intermittent Malfunction, but there are several other possible causes as well, such as ;

Damaged ECM
Erratic camshaft position due to low oil pressure
Camshaft advance mechanism binding (VCT unit)
Incorrect fuel pressure
