Hey guys I'm new to the forum. Can someone help me my check engine light code p0161 (o2 sensor) i need to know what part i need to replace it with. I went to autozone they advised me BOSCH part# 13256 or 15730. I would like to confirm before i buy it. Also looking at OEM ACURA parts diagram shows illustration #9 36531-RCA-A02 SENSOR, LAF. and #10 also looks like it 36531-RDM-A01 SENSOR, FR. LAF
it's for 2006 acura tl Please help me out greatly appreciated thank you
P0161-Heater circuit, bank 2 sensor 2, or the downstream/secondary sensor in the front exhaust.
The two you listed are sensor 1 on each side as designated by the LAF or lean air fuel sensor.
The OEM sensor is:
011 SENSOR, FR. SECONDARY OXYGEN $112.68/$84.51
There could be a problem in the wiring, but it's more than likely the O2 sensor and that's where to start.
Bosch 15730 is an universal sensor
Bosch 13256 is downstream front-correct
The OE sensors go bad, as you have experienced, so I'm not opposed to replacing with a good quality aftermarket unit, especially when it's half the price. I wouldn't use the 15730, or an universal unit, purchase one that's made for the specific application, Bosch, Denso, or RockAuto even carries NTK which is the OEM part.
You can also take a look at the warranty period, don't hold me to the time, Bosch is 12 months, Denso 12 months, NTK 60 days, etc.
can you help me locate that sensor? you mention in the front exhaust is it right front of the engine behind the reservoir tank? I never had check engine light come on. I recently took the car to the shop to replace the front and side motor mounts. Since then the engine light has been on. The mechanic dude said its bank 2 sensor, so what is a good aftermarket sensor to use? is it Bosch 13256 is downstream front-correct?
