Reverse Inhibit Solenoid Control
- Reverse Inhibit Solenoid harness is open or shorted
- Reverse Inhibit Solenoid poor electrical connection
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 (nearvoltage). If the fault detection circuit senses a voltage other than what is expected, the fault line status changes causing the P0801 code to set.
Note:1. Need to look up additional OBD-II Trouble Codes(DTC), use the search box. Enter the 5 character trouble codes in the search box and submit the search. You can repeat the search as many times as you need, one diagnostic code per search.
2. Don't assume a particular OBDii code means the same for other automotive manufacturers as there are many manufacturer specific codes in use.
3. If your trouble codes are for a different automotive, select that vehicle series before searching for the diagnostic codes because not all OBD2 codes used by one manufacture are used by the other manufactures. The search only looks at OBD codes valid for the currently selected manufacturer.
4. This code is for reference only.
