I had a 02 sensor back out causing it to scrape on the ground and become unusable. Gas mileage was poor, ****ty idle, poor performance so on and so forth. And the SES lights came on with codes P1151, P1000.

A friend gave me his 02 sensor from his New Edge Cobra that livened up the engine and cleaned up the idle, gas usage was about the same and the same codes returned. ( I was informed that his sensor would work)

I removed his 02 sensor and put the correct one in for a 02 Gt from Auto Zone. I cleared the codes with the tuner and did the neg. battery brake pedal thing only to have the codes return.

I returned the car to stock to see if the codes are coming from the tune that was installed a day or two before this all happened.

Am I missing anything what's the break down of these codes(meaning) this is really starting to **** me off.

P1151 - lack of HO2521 switches lean see code p2197
P1000 - OBD system readiness test not complete

 

I put the performance tune back on the car and had a friend run a data log of the 02 sensors and bank 2 isn't registering.
Any help with which side is bank 2?

 

Drivers side

 

Do a quick check of under the hood, make sure all vac lines are secured and you hear no whilsting type sound when its running..and double check the pcv and make sure its good.

Check the harness right around the drivers side of the tranny to sort of where it goes around the x-member.. I've seen the harness rub thru the insulation and short/break wires goin to the 02s, causing tons of codes.

 

Thanks for the info guys!
