Reason For U3700 Code

The reason of U3700 OBD-II Engine Trouble Code is Throttle/Pedal Position Sensor/Switch A Circuit Intermittent.

U3700 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine trouble light will be illluminated and the code will be set.

How To Repair U3700 Code

Before starting let's see U3700 repairing process steps:

• Qualified technicians will begin by using a scan tool to access U3700 code stored in the ECU.
• Technicians will note U3700 code present and any freeze frame data associated with them.
• After all, if you sure the engine trouble is finished, the code will be cleared.

B for the vehicle's clutch is giving the wrong voltage readings, there could be an issue with the solenoid, the sensor, the wiring, or with the clutch itself. Shifting may become harsh, and other transmission problems may occur.

This process helps the mechanic narrow down the exact cause of the issue. If the transmission fluid fix did not cause the code to disappear from the PCM, then next step is to inspect the electrical components, and to continue working through possible repairs until the correct issue is found.

Diagnosis Of Engine Error OBD Code U3700

It's essential to diagnose this trouble code. Then are some way which a handyperson should follow for diagnosing the problem that started a U3700 trouble code to be stored

In order to do this, a command can be transferred to the system with scanner or by driving the vehicle under the special conditions that will spark the system. While this is passing keep an eye on the checkup tool data for the result.
