P0906 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0906 can be explained as Gate Select Position Circuit Low. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things. The gate select position actuator is monitored by the transmission control module. The TCM would set this trouble code when the gate select position actuator would not be as per the specifications set by the manufacturer.

We believe that an investment in knowledge pays the best interest. So why not learn more about the P0906 error code? This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

What causes this problem with the Gate Select Position Circuit Low?

• The gate select position actuator might not be functioning properly
• Gate select position actuator harness might be opened or shorted
• There can be bad electrical connection in the gate select position actuator circuit

1. Auto Transmission Shift Solenoid - A faulty Auto Transmission Shift Solenoid can be troublesome. You can always rely on us as we have best auto parts for our customers.
2. Electronic Control Unit - If everything is alright with PCM, then there is surely some defect in Electronic Control Unit. Get it replaced before the situation gets worse.

Here are some steps which you should follow in order to diagnose this fault code:

• A digital volt-ohm meter would be required to diagnose the GSP sensor as well as the circuit between it and the ECM or TCM. A scan tool with live data streaming capabilities may also be needed in diagnosis, as it would help in showing you what the ECM or TCM is seeing.
• Generally circuit issues like loose connections, corrosion, or defective wire harness cause this DTC to be stored, this problem can be caused because of alignment issues.
• First of all you should inspect the alignment of the sensor. The scan tool can be used for this step. You can always adjust it as per the requirement.
• Rotation sensors usually need to be aligned to a “neutral baseline” to properly detect gate select position. If it is off to one side or another, GSP voltages may be skewed to one side or the TCM may detect more than one position at a time.
• Be sure the sensor mounting screws are properly torqued to stop motion of the sensor case.
• The GSP sensors which are located on the shift lever or shift linkage may rely on physical contact, tabs or buttons forming the basis for these sensors or switches. With the passage of time, plastic or metal tabs may become fragile, crook, or smash.
• At least a couple of brands use magnetic micro-switches to sense position, and the magnets have been known to come loose. Make sure to restore the defective parts.
• The next step is to check the circuits.
• For that you will require an electrical wiring diagram, specific to your year, make, and model, to diagnose the circuit running between the ECM and GSP.
• Carefully examine the GSP sensor, connector, wire harness, and ECM or TCM connector for obvious defects.
• Monitor the connectors for corrosion or evidence of water entry, faulty or loose pins. All the connectors should be seated properly. Fix them as per the requirement.
• The ECM and GSP should be disconnected and then the continuity should be checked.
• If they measure more than 5 Ω, then the wire harness should be repaired. If they measure less than 5 Ω, suspect a defective GSP sensor, but do not condemn it until the circuit inspection is finished.
• You should inspect for short circuits between each line and from each line to ground. If you measure less than 10 kΩ resistance, then mend the wire harness.
• If you measure more than 10 kΩ, then the faulty GSP sensor should be suspected.

Common Mistakes When Diagnosing The P0906 Code

• Non observance of the transmission control module
• There can be some faults in the shift lever assembly
• Negligence in the wiring
