Good To Know

Q: Will this sensor need programming after installation? A: In most cases a throttle sensor of this type bolts on and plugs in without dealer programming, though some models may require a throttle relearn. Confirm the procedure for your exact model year before install.

Q: How do I know the sensor is the problem? A: Common signs include erratic idle, delayed throttle response, or fault codes tied to throttle position. Testing the sensor output against specification is the surest way to confirm before replacing.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
