p0707 transmission range sensor circuit low input
P0707 Transmission Range Sensor Circuit Low Input
Description: The P0707 code indicates that the transmission range sensor circuit has a low input.
Definition: This OBD2 code is triggered when the Powertrain Control Module (PCM) detects a voltage signal from the transmission range sensor that is lower than expected. This sensor helps determine the position of the gear selector and ensures proper transmission operation.
p0707 – Transmission Range Sensor Circuit Low Input
Severity: Moderate
Common Causes
p0707 – Transmission Range Sensor Circuit Low Input
Common causes:
- Faulty transmission range sensor
- Corroded or damaged wiring/connectors in the transmission range sensor circuit
- Low battery voltage
- Faulty PCM (Powertrain Control Module)
Common Misdiagnosis
OBD2 Code: P0707
Description: Transmission Range Sensor Circuit Low Input
Common Misdiagnosis: Replacing the transmission range sensor without checking for wiring issues or connector problems.
Common Diagnostic Steps
OBD2 Code: P0707
Description: Transmission Range Sensor Circuit Low Input
Common Diagnostic Steps:
- Check for any additional trouble codes that may be present.
- Inspect the transmission range sensor and its wiring for damage or disconnection.
- Test the battery voltage and ensure it is within the proper range.
- Use a scan tool to monitor the transmission range sensor data while shifting through gears to verify correct operation.
- Check the continuity and resistance of the transmission range sensor circuit using a multimeter.
- Inspect connectors for corrosion, bent pins, or poor connections.
- If equipped, check for any updates or technical service bulletins (TSBs) related to this code from the vehicle manufacturer.
- If necessary, replace the faulty transmission range sensor with a new one and clear codes to see if they return.
