i have a code po37 1st bank 2nd sensor low heater curcuit...

im not sure if with an aftermarket tune and exhaust i should be running the sensor with 2 bung extensions... which is what im using atm. but im goin to try running my stock cat converter to pass smog and need to get rid of the CEL im doubting the converter alone will fix the situation. i drove away with the 02 sensor not installed one day and it banged around down the street till i pulled over and wired it back up.

my guess is its broke... i dont know but should i get a cel with aftermarket tune and exhaust? with 2 bungs extension? if i am then i dont need to buy a sensor... but to bypass buying a 400$+ sensor i need help with some technical info...

does anyone know the ohm readings this sensor is supposed to send to the computer? there is 4 wires and i was going to make a plug in harness with resistors so i dont have the CEL if anyone could give me any info id really appreciate it i need to smog the stupid thing...!

id assume there would be 2 resistors one for each set of 2 wires on the harness

HELP PLEASE

 

remove the rear o2 completely and use tephra's sim patch + o2 cel disable to pass inspection.
you'll need a cable to reflash that.
