This summary uses the existing diagnostic information shown in full below.
This means that the car's computer is having trouble figuring out what gear the car is in because the signal it gets is not steady.
The P0918 code is triggered when the transmission control module (TCM) detects an intermittent signal from the gear shift position sensor or circuit.
The gear shift position sensor sends signals to the TCM to indicate the current gear position. If the signal is inconsistent or intermittent, the TCM cannot accurately determine the gear position, leading to the P0918 error code.
• Check Engine Light is on
• Transmission may not shift properly
• Vehicle may not start
• Faulty gear shift position sensor
• Damaged or corroded wiring/connectors
• Faulty transmission control module (TCM)

Moderate
• Toyota Camry
• Ford F-150
• Honda Accord
• Regularly inspect and maintain wiring harnesses.
• Keep connectors clean and free from corrosion.
• Perform routine transmission maintenance.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Avoid driving the vehicle if shifting issues occur.
Check with your vehicle manufacturer for warranty coverage on transmission components.
This code has been associated with issues in vehicles with electronic gear shift systems, particularly in models with higher mileage.
Moderate – Addressing this issue promptly can prevent further transmission problems.
Driving with a faulty gear shift position sensor can lead to unsafe driving conditions. Address the issue as soon as possible.
• Vehicle in Park or Neutral
• Engine running
The gear shift position sensor is typically located on the transmission housing or near the gear shifter.
Q: Can I drive with a P0918 code?
A: It's not recommended to drive with this code as it can lead to unsafe driving conditions.
Q: How do I reset the P0918 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
