***my Car Wont Start After Playing With O2 Sensor? Assistance Needed.... ***

[thirtythree-II]

I was testing the volatge coming from my o2 sensor on my r33 gtst s2 to see if its operating correctly by connecting a multi-meter to 2 of the 3 terminals, negative and positive. I incorrectly tried connecting it another way through the meter which caused the car to have a rough idle and then shutoff. Now it will not start at all. It cranks over and idles for a split second then shuts off. Ive checked all fuses that I know of and none are gone. Ive also reset the computer and this has achieved nothing. I think i've fried the internals of the o2 sensor, so im thinking a new one would solve the problem. Any assistance would be greatly appreciated. Cheers.

It won't have anything to do with the O2 sensor - the ECU doesn't need it to start (only on cruise).

Exactly how did you connect the meter? You only need to measure V between pin 2 and earth, and the reading should oscillate between 0 - 1V, with engine at operating temp and constant throttle.

I had the negative to the black and grey wire on the o2 sensor and the positive to the red wire. This was all fine until I change the connections on the actual meter.

the o2 sensor shud be in limp mode if its fu(ked. should still drive. however not being able to start the car wont have anything to do with the o2 sensor.

just grab another one to be safe.
