O2 sensors replacement (1 Viewer)

[njfzj80]

Greetings from Newbie Land.

The day after I purchased my LC the check engine light came on. I could feel my wallet getting lighter. I took it to the TOy dealer and they said that the O2 sensor was the culprit. They recommended swapping out both. Ok I thought, and left it at that (what a newbie). A few weeks ago i was checking the exhuast line (locating the rattle in the heat shields)and I came across the O2 sensors. The one placed after the cats was clean and shiny. The sensor placed before the cats looked as though it had gone 90,000 miles. Could the dealer have charged me for two new sensors and only installed one? How can I find out? The other thing, is that my check engine light has been acting up again...coming on one day and shutting off the next. Should I just take it to the dealer or autozone to get the diagnostic code? I'm a little paranoid because some dealers in the area have been known for charging for repairs/maintenance that were never performed. Jersey!

Thanks.

I think you've answered your own question: take it back to the stealer who did the O2 replacment. Show them what you described and show them what they charged you. I suspect they'll correct the situation. It may also solve your CEL issue, but I'd get that CEL scanned before you take it into the dealer.

You should be able to at least tell if they charged you for two O2 sensors. Check the invoice and see what they charged. I think the going rate for an OEM O2 sensor is in the $180 to $200 ish ball park. You can call C-dan and get the list price for them. Don't be shocked if they charged 10 or 20% over list. The labor should be separated out.

Definitely go to Autozone and get it scanned for free. You can post up the code here if you need to know what it's for and what the probable culprits are. You want to arm yourself with as much info as possible, to make sure they aren't taking you for a ride. If you just go in there questioning the second sensor, they're probably going to feed you some bolagna, pat you on the head and send you on your marry way.
