I have an 89 cherokee and i cant figure out why my emissions light is on, and im just wonderin can i pass emissions with that on?

 

nope.. they wont even pass one with the check engine light on.. in Cal. and Ohio, anyway..

there is some stuff that you spray on a sensor to unstick it.. ask at the auto parts store.. i bet they would have it

good luck

 

There is no triggerable emissions light on an 89....

It is set off by a timer under the dash. Pull the timer.. the light will never come on again. If you look under the dash towards the heater controls, it is a smoked plastic box with white gears inside. Unplug it.. you are done.

Yeah unplug it! That light indicates its time to go back to the dealer to buy another timer and O2 sensor and pay the 1 hr flat rate $$.

It is there as a "reminder" to check your emissions equipment (Oxygen sensor, EGR, etc) since there is no CEL in a renix cherokee...

 

X2. Unplug it

 

It tells you when you reach 82,500 miles and to change the 02 sensor,they were changed out by the dealer. I doubt you can still get them. I would just remove the bulb and it will be fine,not the same as check engine light.

 

This addressed a problem with a 1989 XJ Laredo that I just bought. The box in my XJ was closer to the vent under the steering wheel, but it did just what the post said it would do. Thanks. XJ forum!
