I have Code P0150. I'm trying to check the harness to make sure its working before i buy a new O2 sensor. The Mitchell program said:

"Turn ignition off, disconnect front left o2 sensor harness connector and ECM harness connector. Using an ohmeter check for continuity."

I have an Ohmmeter, but my wires are too short to meet under the dash from infront of the engine, where the o2 sensor is located


...lol am i misreading something??

use some wires to extend the meter leads...

or short each sensor wire to ground and measure it that way...

remove positive from battery first obviously

hey, thanks very much.

Do you know what is the resistant of a good o2 sensor vs a bad one?
