How do I fix code P0801 SATURN

Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

Cost of diagnosing the P0801 SATURN code

Labor: 1.0

The cost of diagnosing the P0801 SATURN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.

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.

Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)

P0801 Saturn Description

An ignition voltage is supplied to the Reverse Inhibit solenoid. The Powertrain Control Module (PCM) controls the solenoid by grounding the control circuit via an internal switch called a driver. The driver supplies the ground for the component being controlled. Each driver has a fault line which the PCM monitors. When the PCM commands a component ON, the voltage of the control circuit should be low (near 0 volts). When the PCM commands the control circuit to a component OFF, the voltage potential of the circuit should be high (near battery voltage). If the fault detection circuit senses a voltage other than what is expected, the fault line status changes causing the P0801 code to set.
