Code P0801 Saturn Description

The P0801 diagnostic trouble code for Saturn vehicles indicates a problem with the Reverse Inhibit Solenoid Control Circuit. This circuit is responsible for controlling the operation of the reverse inhibit solenoid, which is a component that prevents the vehicle from being shifted into reverse while driving forward. When this code is triggered, it means that there is a malfunction or issue with the circuit that controls this solenoid.

Common Causes of P0801 Saturn

  1. Faulty reverse inhibit solenoid.
  2. Wiring issues or electrical connections related to the solenoid control circuit.
  3. Corrosion or damage to the circuit components.
  4. Defective transmission control module (TCM).
  5. Issues with the vehicle's computer system or software.

Symptoms of P0801 Saturn

  1. Inability to shift into reverse gear.
  2. Delayed or rough shifting when trying to shift into reverse.
  3. Illumination of the Check Engine Light on the dashboard.
  4. Transmission slipping or erratic behavior.
  5. Vehicle stalling when attempting to shift into reverse.

How to Fix P0801 Saturn

  1. Begin by conducting a thorough inspection of the reverse inhibit solenoid and its control circuit.
  2. Test the solenoid and circuit for proper operation using a multimeter to check for continuity and voltage.
  3. Replace the reverse inhibit solenoid if it is found to be faulty.
  4. Repair or replace any damaged wiring or connectors in the control circuit.
  5. Reset the vehicle's computer system to clear the trouble code and test the vehicle to ensure proper operation.

Cost to Fix P0801 Saturn

The cost of repairing a P0801 code for a Saturn vehicle can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, the parts for this repair, such as a new reverse inhibit solenoid, may cost between $50 and $150. Labor costs can range from $100 to $300, depending on the shop's hourly rate and the time required to complete the repairs.

When is the Code Detected?

When the Reverse Inhibit solenoid energizes, the operator can shift the transmission into reverse. The Powertrain Control Module (PCM) enables the Reverse Inhibit solenoid whenever vehicle speed is below 5 mph. When the vehicle speed is above 5 mph, the PCM de-energizes the solenoid, which prevents the operator from shifting the transmission into reverse.
