Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / October 2006Need o2 sensor advice for '03 Mazda MPV
Where do I find the o2 sensors on my '03 Mazda MPV? The check engine light went on, so I found out it's the 1 and 2 sensors in bank 1. I'm not as car-literate as I would like, so my son is helping me (actually he'll be doing most of the work, he loves working on cars) but I need advice on where to get two sensors cheaply, and where to look for them. Thanks in advance, John You can go to get quotes at some autopart malls like Autozone, O'Reilly, etc. I think the 02 sensors cost around $60 and something for each. But are you sure that you have to replace the O2s? Please post your check engine codes here. Ace > Where do I find the o2 sensors on my '03 Mazda MPV?

Fix the P0300 code first, it's possible that will also take care of the O2 sensor codes. The P0300 code could be as simple as a tune up. You mean simple tune up as in "change the spark plugs and filters" tune up? Now that I can do this weekend. Even if all the problems don't go away, it's still overdue. Thanks for the advice. > > >From a product called CarChip: > > [quoted text clipped - 9 lines] > Fix the P0300 code first, it's possible that will also take care of the > O2 sensor codes.

I don't want Walmart brand, (does such a thing exist yet?) but just looking on the internet briefly gave a HUGE range in prices. Would you pay $200 for a part someone else offers for $50? Some after market parts are just as good, others aren't. I don't know, so I'm asking for opinions. Thanks for your time. > Where do I find the o2 sensors on my '03 Mazda MPV?

Look around the exhaust manifolds and just after the catalytic converters, but don't replace anything without first performing the tests recommended in the factory and Mitchell manuals because computer error codes are often just rough indicators of a problem. The o2 sensors themselves may be fine, and there may instead be a problem with something related to them, such as their cabling, especially since it's unusual for 2 of these sensors to fail simultaneously. > The o2 > sensors themselves may be fine, and there may instead be a problem with > something related to them, such as their cabling, especially since it's > unusual for 2 of these sensors to fail simultaneously. I don't think they did fail at the same time, the van has been running a little rough, but since I wasn't running it, and my wife didn't say anything at the time, I didn't put two and two together. Now it's bad, and off the road. I'll try to get specific engine codes, and voltages if I can, and post them this afternoon. |
