O2 sensor and tire low light

[ashexxx]

Just purchased an 08 H3 Alpha, and I'm wondering the location of bank 1 sensor 2. Is this upstream or downstream, and is it an easy swap? I also have a low tire light, and after filling them all up, including the spare, it's still on. I'm reading that there is a tool to reset the low tire light? If I disconnect the battery, will it reset? Thanks!

Sensor 2 is downstream, and bank 1 is driver's side.

Low tire light - I would recommend resetting the TPM sensor according to the procedure in the owner's manual to first make sure that it's reading the correct four TPM sensors. (Note - early 07s and earlier have five sensors; later trucks do not have one in the spare).

Have you driven it since refilling? They do go into a dormant mode and need to be driven to activate new sending to the computer.

Thanks that helps a ton! Been googling the placement of the sensors and not finding anything. I've driven it since. Just read through the whole manual. Are you talking about resetting it on the instrument cluster, or the crazy sequence of pairing them till the horn beeps?

Horn beeps. May or may not fix the issue, but at least you get an important troubleshooting step out of the way.

There is a sequence in the manual that has you turn the key, do something to put the car in some detection mode, then fill or deflate the tires for 10 seconds in a certain order till you hear the "horn chirp" something crazy like that. I'll try it, hopefully the person that wrote the manual didn't have a sense of humor and I won't be looking like a jack ass waiting for the horn to beep.

No, it's not a practical joke, just seems that way. I have to do that when I rotate my tires.
