C3725 OBD-II Diagnostic Chassis (C) Trouble Code Description

C3725 engine trouble code is about Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical. Throttle/Pedal Position Sensor/Switch A Circuit Intermittent and Crankshaft Position Sensor A Circuit Malfunction causes most of code C3725.

Reason For C3725 Code

The reason of C3725 OBD-II Engine Trouble Code is Throttle/Pedal Position Sensor/Switch A Circuit Intermittent.

C3725 the main thing to check is to verify the operation of the VCT solenoid in the engine. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. Refer to vehicle specific service repair manual to perform component tests for the VCT unit.

How To Repair C3725 Code

Before starting let's see C3725 repairing process steps:

• Qualified technicians will begin by using a scan tool to access C3725 code stored in the ECU.
• Technicians will note C3725 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.

The transmission uses hydraulic pressure, controlled by solenoids, which are controlled by the PCM, to shift gears and provide torque converter lockup. The PCM calculates the necessary amount of pressure at any given time to optimize vehicle operation.

A digital volt/ohmmeter may be necessary to compare the voltage reading with the manufacturer's specifications. The mechanic should always clear the code and retest the system after each possible repair, to ensure that they've made the proper diagnosis.

Diagnosis Of Engine Error OBD Code C3725

It's essential to diagnose this trouble code. Then are some way which a handyperson should follow for diagnosing the problem that started a C3725 trouble code to be stored

Depending on your vehicle you may have a vacuum operated selector or a vacuum solenoid if it's electrically actuated. In the case of the former, a hand held vacuum pump will have to be used to testit.The purpose is to see if the internal stopcock is getting turned by the selector, motor or solenoid. 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.
