P2342 engine trouble code is about Crankshaft Position Sensor A Circuit Low Input. Fuel Rail Pressure Sensor Circuit Malfunction and Engine Shutoff Solenoid Malfunction causes most of code P2342.

Reason For P2342 Code

The reason of P2342 OBD-II Engine Trouble Code is Fuel Rail Pressure Sensor Circuit Malfunction.

P2342 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 P2342 Code

Before starting let's see P2342 repairing process steps:

• Qualified technicians will begin by using a scan tool to access P2342 code stored in the ECU.
• Technicians will note P2342 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.

If nothing is done to repair the persistent P2342 code, the ECU will put the vehicle into a limp mode. This mode limits the top speed and reduces engine power greatly to protect the engine.

Diagnosis Of Engine Error OBD Code P2342

It's essential to diagnose this trouble code. Then are some way which a handyperson should follow for diagnosing the problem that started a P2342 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.
