The P0907: Gate Select Position Circuit High refers to a condition where the voltage in the gate select position circuit is too high. This can interfere with the transmission’s ability to detect the correct gear position, leading to shifting problems or incorrect gear engagement.
P0907 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0907: Gate Select Position Circuit High |
| Is it serious? | Yes, improper gear selection can cause drivability issues and damage to the transmission. |
| Possible causes | – High voltage in the gate select position circuit – Faulty gate select sensor or actuator – Wiring or connector issues |
| How to diagnose? | – Check the circuit for high voltage – Inspect wiring and connectors – Replace faulty components if needed |
P0907 Meaning
The P0907 code indicates that the gate select position circuit is registering a higher-than-expected voltage. This could result from faulty wiring, connectors, or a malfunctioning gate select sensor or actuator. High voltage in the circuit can cause incorrect gear position detection, leading to improper shifting or failure to engage the correct gear.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other related codes to provide more details about the issue. | OBD-II Scanner |
| Inspect Wiring and Connectors | Visually inspect the wiring and connectors associated with the gate select position circuit for damage, corrosion, or loose connections. | Flashlight, Multimeter |
| Check the Circuit for High Voltage | Use a multimeter to measure the voltage in the gate select position circuit and compare it to manufacturer specifications. | Multimeter, Vehicle Manual |
| Test the Gate Select Sensor or Actuator | Use a diagnostic tool to test the performance of the gate select sensor or actuator and replace if necessary. | Diagnostic Tool, Replacement Sensor/Actuator |
| Replace Faulty Components | Replace any damaged wiring, connectors, or faulty sensors or actuators found during testing. | Replacement parts, Tools |
| Clear Code and Test Drive | After repairs, clear the code and take the vehicle for a test drive to confirm the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the vehicle after the test drive to ensure that the P0907 code does not return. | OBD-II Scanner |
