Question From hardtimes123 on oxygen sensors

have a 2003 hyundai santa fe need to find out how many o2 sensors i have and were they are. thanks

Response From Hammer Time

Should we consult a crystal ball to find out what engine you have?

Response From Discretesignals Top Rated Answer

Going to have to use your crystal ball tonight, HT. The light bulb burnt out in mine. Won't get another from China until next week.

Response From Hammer Time

I couldn't survive without mine.

Response From hardtimes123

Response From Hammer Time

Check engine light on for four months

Showing 2 out of 3 Posts | Show 1 Hidden Posts
Question From forum1167 on Check engine light on for four months

So, my check engine light has been on for four months. I drive a 2005 hyundai sonata. It has 67,000 miles on it. I havent gotten it fixed yet because I was quoted a high price for repairs. I want to know if this is a reasonable price for repairs. I brought my car to Firestone Complete Auto Care and they said:

Recommended Services not authorized by customer:

exhaust $1,114.65
Leaking $999.99
remove and replace catalytic converter $76.50
gaskets $12.99 (x 2)
studs $6.09 (x 2)
engine sensors $189.99
remove and replace oxygen sensors-rear, one or all $51.00
total: 1,455.31

They said my exhaust was leaking so that is why my check engine light has been on for four months. So, my questions are:
Is this price reasonable for this repair?
Is this a much needed repair or is it okay to continue driving my car with the check engine light on?

Thanks. Let me know if you need any more details.

Response From way2old

Go have the trouble codes read and post the EXACT code number back here. With that information, we have a better place to start helping you. Thanks.

Response From forum1167 Top Rated Answer

*** UPDATE ***
since then, i have gone to a reputable mechanic and have been very happy. they said:

#P0139 OXYGEN SENSOR SIGNAL SLOW
FIRST REPLACE OXYGEN SENSOR THEN RECHECK FOR OTHER PROBLEMS. VEHICLE CATALYTIC CONVERTER MAY NEED TO BE REPLACED
1 OXYGEN SENSOR (B1 S1) $291.44
1 OXYGEN SENSOR (B1 S2) $189.99

Much better than Firestone, and they explained everything to me. They said if in 6 weeks the check engine light comes on again, then the vehicle catalytic converter may need to be replaced.

2000 Hyundai Sonata - Hesitation on Hills

Showing 4 out of 5 Posts | Show 1 Hidden Posts
Question From WillCA4 on 2000 Hyundai Sonata - Hesitation on Hills

2000 Hyundai Sonata GLS, V6, Auto, 76K miles. Having problems with hesitation-stumble/power loss primarily when on hills - at any speed. If I downshift to raise rpm's problem goes away - put back into drive and it comes right back. Tried so far: changed the air filter, cleaned the mass air flow sensor, cleaned the throttle body, replaced the pcv valve and it's hose, added fuel injector cleaner to gas tank. Other info - an oxygen sensor was replaced at 71K, speed sensors were replaced at 50K. Thanks for any help you can offer.

Response From WillCA4

Thanks for the info. I checked the plug wires (all 6 lead to a single coil) and coil and did not see any damage or burt issues. The plugs were replaced about 25K ago with Bosh Platinum. I started the car and it was now running rough, and after driving about 1 mile gave check engine message. Went back and checked the code: PO305 - Cylinder 5 Misfire detected. Pulled the plug (not sure of the firing order on this car, but assumed 5th was center plug closest to front of car) and it did not look bad - neither white nor black and oily. If you think this is still ignition problem then I will likely replace all the plugs, then wires, then the coil to try and solve this. If you think something else please let me know, thanks again.

Response From ltaylor


Response From way2old

Sorta looks like you are checking the wrong plug. Look below.


Response From paulklux Top Rated Answer

It sounds like you have an ignition problem
There is three main problems the sonata has with ignition.

1) Spark plugs - generally if worn or if just recently replaced make sure they are Hyundai original plugs as some non genuine experience the fault you have experienced
2) Coils - remove and look for burn marks around coil
3) Ignition leads if it is type with just two ignition coils - again you will see burn track marks on them - insulate the stems of coils and leads wth insulating tape
