Help! Voltage Problem? (P0428)
So my check engine light came on yesterday and after I took the car to autozone for a check engine light diagnosis, the following came up:
OEM Number to Cross: P0428
The PCM has determined that the voltage signal from the catalyst temperature sensor for bank 1 is too high for the current engine operating conditions. (bank 1 identifies the location of cylinder 1, while bank 2 identifies the cylinders on the opposite bank)
Since I am kind of technologically challeneged, I was wondering if anyone could translate that into plain english for me? I am guessing my engine is running hot? But the temp sensor seems normal.... Any help will be sincerely appreciated!
Thanks!

Cat might be clogged.
What year is your car? Mileage?
Cat is covered under emissions for 8 years, 80,000 miles.

It's a 2004 RX8 with 30,000 miles. My warranty is no longer in effect, but it's nice to hear about the 8 year CAT warranty . Has anyone ever come across this problem before?

yeah, maybe it's gunked up or something knocked it loose?
crawl under there and take a look.
Any other codes come up or just the 0428?

No more codes, jus that one. Come to think of it I think I did scrape the cars bottom while backing out recently...I will check it out! Umm what exactly am I looking for btw, any specific location for the O2 sensor?
