What the P0902 code means

The P0902 is a generic OBD-II powertrain code, which means it applies to all makes and models of vehicles from 1996 to the present.

What causes the P0902 code?

There may be one or more causes for the P0902 code. It could be due to wiring or a short to your ground. It could also be your clutch actuator, ECM, PCM, or TCM. To determine the exact cause, you will need either to investigate the problem yourself using the proper diagnostic tools, or consult a professional technician.

What are the symptoms of the P0902 code?

Your Check Engine light may come on. Your vehicle may also suffer from poor acceleration and decreased fuel economy.

How does a mechanic diagnose the P0902 code?

The clutch actuator cylinder is the metal rod that connects to your pedal each time you depress the pedal to engage the gears. A mechanic will first do a visual inspection, checking for unplugged harness connections and corrosion or loose wires on your connectors.

You should always begin by inspecting the wiring and connectors in your vehicle. To do this, use a digital volt/ohmmeter and an OBD-II scanner. After inspection, be sure to replace or repair any shorted, damaged, disconnected, or corroded wiring, and connectors.

Remember to record all freeze frame data and codes. Afterward, clear the code and then test-drive the car to see if the code reappears. If the code does not reappear instantly, you may have an intermittent condition, which is harder to diagnose. Unlike most diagnostic codes, an intermittent condition code is often better left to a professional because of the amount of circuitry involved. Also, an experienced professional may have a specialized scanner, such as a Tech II or an Auto hex, which will help them determine the area of the malfunction more easily and in less time.

How serious is the P0902 code?

The P0902 code is very serious and, unless you are very skilled and have the proper tools, should be looked at by a professional technician. In many cases your car will not start if it is showing a P0902 code.

What repairs can fix the P0902 code?

First, you or your technician should reprogram the transmission control module. If this does not solve the issue, you will need to replace the clutch It is important that you either do a fair amount of research or take your vehicle into a professional because you might misdiagnose the problem and spend money on parts or labor that you do not need.

Sometimes this code appears on trucks with oversized tires or upgraded performance drivetrains. With an advanced scan tool that is able to read the engine functions, you will need to monitor the duty cycle commanded to the control solenoid. Please know that you will need to monitor the solenoid during engine operation.

Using an oscilloscope or graphing multimeter set on the duty cycle scale, connect the negative lead to ground that you trust, and then connect the positive lead to the wire terminal at the solenoid itself. The reading on the multimeter tool should match the commanded duty cycle on your scan tool. If these are opposite, the polarity may be reversed. If this is true, connect the positive lead on the other wire terminal to the solenoid and test again to verify. If the signal detected from the PCM is on all the time, there may be a problem with the PCM. But PCM problems are rare.

Additional comments for consideration regarding the P0902 code

Many older vehicles have temporary sensor problems that occur due to long periods of stress on the drivetrain. It is true that a P0902 can be difficult to diagnose and repair, but it is not as difficult to fix as some other codes. If you do decide to do this yourself, make sure that you research ways to repair this issue and obtain the proper diagnostic equipment before starting.
