Park/Neutral Switch Input Circuit High

36 brands affected · Generic SAE J2012 description.

Key terms: SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

1What it means in plain English

This range normally covers the transmission control system, but some manufacturers use P07-P09 codes for unrelated functions (fuel pump control, air-mix motors, lighting or windows). Check the description before assuming it is a transmission fault.

2Common causes

Low or dirty transmission fluid
Faulty shift solenoid
Faulty speed sensor
Wiring or connector fault
Internal transmission wear

3Can I drive?

Caution · drive with care

If the transmission slips, jerks, will not shift, or a transmission temperature warning is on, stop driving and let it cool: continuing can cause expensive damage. If the code names a different system (for example the fuel pump), treat it on its own terms; a fuel-pump control failure can stall the car, so have it checked before driving further. Otherwise drive gently to a workshop.
