Good To Know
Q: Will this sensor work with my tractor's existing wiring harness? A: Yes, this sensor uses the same connector and pinout as the original RE61812, so it plugs directly into the factory harness without modification.
Q: How do I know if my sensor needs replacing? A: Common symptoms include poor fuel economy, rough idling, or a check engine light related to intake air temperature readings. Replacing this sensor restores accurate data to the ECM.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
