Oxygen Sensor (OEM Denso)

The 1988 only, 4-wire heated oxygen sensor has the correct length harness and body grommet built on.

Denso is beginning to discontinue sensors for the 1989-1995, please email with your truck details and I can check to see if it still available. I need to know long bed, short bed. 2WD or 4WD and California or Federal emissions

Some 1989-1995 use 2 sensors, one before the convertor and after it. Order quantity 2 if you need both. 

Your O2 is VERY crucial. It tells your engine computer if your engine is running RICH or LEAN. If it’s defective, it will give the WRONG reading which WILL GREATLY effect driveabilty and performance. If you can’t test it....REPLACE IT!

****FOR 1989-1995 IN THE NOTES FIELD AT CHECK OUT, LET ME KNOW IF THE TRUCK IS 2WD OR 4WD AND LONG BED OR SHORT BED****

(there are close to a dozen variations for those years and I need to know your configuration so I get you the correct one)
