Please check below for your specif P1389 code. Fuel Rail Pressure Sensor Circuit Malfunction and Cylinder 1 Injector Circuit Low causes most of code P1389.

Reason For P1389 Code

P1389 DTCs may also be triggered by engine faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.

How To Repair P1389 Code

Before starting let's see P1389 repairing process steps:

• Qualified technicians will begin by using a scan tool to access P1389 code stored in the ECU.
• Technicians will note P1389 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 pressure control solenoid 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.

The computer installed in each fuel-injected vehicle has to be aware of two factors before it can solve the proper cold-start air/fuel compound: the engine coolant temperature and the exterior air temperature. Your symptoms are exactly the same to a faulty engine coolant temperature sensor (ECT). The computer is measuring an air/fuel compound that is excessively meager.

Diagnosis Of Engine Error OBD Code P1389

It's essential to diagnose this trouble code. Then are some way which a handyperson should follow for diagnosing the problem that started a P1389 trouble code to be stored

It's always good to rule that out.

The coming step is to run a introductory examination of all the electrical circuits, connectors, wiring etc for damages similar as becks, erosion, fraudulent legs etc. All of these will have to be repaired or replaced. After that's sorted, clear the canons and go on a test drive to see if it resets. In case it resets, you'll have to continue your opinion. 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.
