Help! O2 sensor problem

[Just_Another_Dj]

Hey all,

I just installed a pod filter on my 1989 Celica, pulled the air box out, attached the pod filter to the o2 sensor and clamped it. Now it wont start.

When i pulled off the airbox i disconnected the o2 sensor plug about a cm then plugged it back in. It looks like its just a pin connecting, maybe soldered.

Does anyone have any idea why the air sensor isnt responding now?

Help much appreciated!

Cheers.

It's not your O2 sensor, I can tell you that. It's either AFM/MAF (not sure on your engine) or an intake temp. sensor. Even then, I doubt it's preventing your car from starting (if it was the first two, then your car will start and run pretty roughly/stall).

Will the car turn over with the starter motor?

Yeah car turns over just fine.

Its getting air and the only thing i took out was the air box.

sorry by O2 sensor i ment air flow meter. I took the air box off from the AFM then attached the pod from there.

So your car turns over, but won't start? Reset the ECU (pull the fuse in the engine bay fusebox, wait ten seconds then replace) and see if that works. The other obvious thing to do is put your airbox back in and see if the car runs.

I know with some cars (newer Mazda 3's definitely), if you remove the airbox and add a pod filter, the ECU will show an error on the dash.

Pulled the ECU fuse and reset ECU, still not starting. I will put the air box back on and try to get it working. Keep you posted.

unless of course you have damaged the sensor or its connectors when removing the airbox assembly. otherwise, it 'should' start fine.

Hey, put the airbox back on, most likely i damaged the cable going to the ECU or the actual sensor, so looks like i'll have to replace that.

Thanx everyone for the help.

Cheers.

Take a photo and slap it on here. Its not that hard. Maybe we might have a better idea of whats going on.

Ok all good now. Seems that when I undid the screws mounting the AFM plug I killed it! Found one at the wreakers for $10 and

its all working fine now. Important tho is that when the AFM fails the ECU wont get a signal and the plugs will not get electricity!

But yeah easy fix.
