P0817 OBD-II: Starter Disable Circuit/Open
P0817 Severity
Should you fix P0817 yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P0817?
The engine computer (PCM) verifies that the transmission is in Park/Neutral before allowing the vehicle to crank. If the Transmission Control Module does not tell the PCM it is okay to crank the vehicle, code P0817 will be set.
