Codes P0053 & P0135

[walkerdog]

my check engine light has caem on and throwing these 2 codes . where should i start? i don't want to change the oxygen sensors and that not be the problem . the probable causes show

short circuit

relay defective - where is this relay

oxygen sensor (SENSOR 1 BANK 1)

[bill190]

This is a heated oxygen sensor and the computer is detecting that there is a problem with the heater portion not working. And the other code is caused because the heater is not working.

 

This could be a fuse, wiring, a connector with a poor connection, or the heater in the oxygen sensor (replace oxygen sensor in that case).

 

Generally oxygen sensors should be changed every 60,000 miles as a regular maintenance item. And when I replace mine, I get better gas mileage (also my engine is more lively). So I see this as a money saving thing myself.

 

But just about everyone I know will REFUSE to replace their oxygen sensors for some reason???

 

Anyway information for troubleshooting and/or replacing this would probably be in an aftermarket repair manual for your vehicle (auto parts store). But this information would for sure be in a Factory Service Manual set for your vehicle which you can order from your dealer.

Sorry to resurect an old thread, but is there any way to tell which sensor is bad?

The P code will direct you to the sensor. Bank 1 Sensor 1 is the drivers side, pre-cat O2 sensor. Sensor 2 would be post cat. Bank 2 is passenger side. The bank #'s tell you cylinder side #. #1 cylinder is driver side. #2 cylinder is passenger side

All my Autocal tells me is P0053 or P0135. Is there a way to decode that further or will I have to carry it to my mechanic?

 

Ill probably just end up replacing all 4(106K and probably still the factory sensors), but Im just curious as to how I could determine which sensor went bad.

 

Also, which brands of sensors do you recomend avoiding? Ive noticed the Bosch seems fairly reasonably priced (cheap). I also know that with most products, you gt what you pay for, but I dont want to overspend for no reason.

P0135 O2 Sensor Heater Circuit (Bank 1 Sensor 1)

[tyhuck]

OK, cool. Any input as to brands of sensors?

[txab]

IMO, not Bosch

[tyhuck]

I think the next step up was AC Delco, so Ill just go with those I guess.

I always try to use OEM. With that being said the last one that I replaced was on my wife's Pontiac Montana van. The sensor was the one that came from the factory. And I replaced it with a AC Delco. A couple of weeks after I replaced it I looked at the old one with a magnifying glass. It had the part # etched on and made by Denso.

[txab]

Denso makes many of the OEM

[tyhuck]

Rock Auto listed Denso as the factory manufacturer for the O2 sensors. I hope there isnt a difference between the different positions because I just bought 4 of the same sensors. They only listed a single part number, where AC Delco listed a different one for pre-cat and post-cat. is there a difference? If so, Im gonna have to cancel my order.

My truck uses the same part number in all positions....

Thanks. It never occured to me to look, but with the rain we got yesterday and the day before, I probably wouldnt have looked underneath it anyway.
