Because of the age of your car, you could change your oxygen sensor first. Have it checked to see how this effects your readings. If this doesn't help replace the catylitic converter. If your engine is in relatively good shape this action should solve yourc.o. problem Good luck!

    how many oxaigen cebcers do i have and wear is it located

  • eric r barnes Jun 03, 2010

    The oxygen sensors are located, one in the exhaust manifold & if you have two sensors, it is usually in the rear of the converter. If it is a V6, one on each side of the exhaust manifolds usually but no more than two. Hope this helps. Again good luck. Also there is a special tool you need to remove these that can be purchased at any good automotive store.

    Yes its much easier replacing the O2 sensors. YOu can just remove the old on and replace the new one. No hassles, you just need to use a special socket for the O2 may sometimes be deep.

Only high-level brake light works. What's wrong?

Your lower brake lamps are wired through the multifunction switch. The high-mount brake lamp isn't wired that way.

At the lower rear, the turn and stop use the same bulb filament, just not at the same time.

I'd have to check circuits to and from multifunction switch. Sometimes you can get under the dash, find wiring harness to/from steering column, If you can find the proper color wire for lower brake lamps, see if voltage on that wire with brake activated, if no voltage, the problem could be the wiring in steering column or multifunction switch.

Have a 2009 Nissan Quest I can't turn the heat off. Just stays on a high level of blowing out heat .

If you have a fan that has different speed settings (1234, or low med high etc) and the only one that works is high - then the blower resistor pack has failed. If you have a climate control unit (where you just pick a temp you want) then the fan is controlled by the heating system and it sets fan speed. If you have climate control style try lowering the temp to a lower setting (current temp in vehicle) and see if fan slows down. If not then climate control unit or fan resistor bad. If dial type and you get nothing on lower settings (only high works like mentioned above) you need to change blower resistor. It is located under dash near the fan itself. Look for small unit bolted in duct near fan with wire plug going to it.

How do I check trans fluid

park car on a flat surface, then find the transmission dipstick. start car and let it run then pull dipstick out wipe it off and re-insert dipstick and remove it again and look at the bottom of it keeping the bottom of the stick down so oil does not run up the dipstick. check where the oil is on the dipstick and it should be between the lower mark and the upper mark, as long as the level is not above the high level or below the lower mark.

545rfe oil level is too high,how to regulate

The oil LEVEL is too high, or the oil PRESSURE is too high?

To lower the oil level, just drain some off. Doing this will naturally lower the oil pressure, as well.

Rear air suspension

The air system does not lower when you get out, it levels the car and stays level, but is you put weight in trunk and people sitting in the back seat and the car lifts to level out with the weight and then you remove all the weight and rear end is to high up then there is a problem.
These bags do not lift that high, if you hear the solenoids make sure it is not lower , measure.Also, the release of the air is very slow, make sure it is not lower, if you hear the solenoids open the car may be lowering very slow. check the height.If you are sure its not lowering then you may be correct in saying the level sensor may be bad. the only other part would be the solenoids but i would start with the level sensor as the air is going into the bags.
I quick test to check solenoids at bags is to start car and go rear the rear and locate the sensor, remove the arm from the control arm and bring it down so computer thinks car is to high and see if air is released. caution don"t stay under the car as it will lower down slowly. if it starts to lower then turn key off and reconnect lever and replace sensor.there is a company we use that is real good at this air bag system and prices are good with quality parts.

High HYDROCARBONS on emissions test. I have took my 97 Cabrio to emissions test and failed due to High Hydrocarbons. but states the Catalytic converter is fine. what eles could cause high HC levels?

first thing to do is change the air filter. even if it appears clean, the airflow can be blocked enough to affect the petrol air ratios in the engine which will give high HC readings.
changing the spark plugs can give a cleaner spark, and better ignition, with lower HCs. high HCs could also be caused by traces of oil getting through worn piston rings and valve stem seals and burning in the combustion chamber. there are many oil additives that can help stop this and reduce HC levels as well.
hope these suggestions help

Hi duane i drained old antifreeze and add new one eng ran 10 min and high temp check eng came on guage is on H what do i do?

Let it cool down and check fluid level. fill leave cap off and start the engine as level lowers fill until starts to overflow and replace cap. Warning lights could be from an "air bubble" causing a sensor to see low fluid level.

The heater in my 2002 Dakota works only at the very highest setting. There is no power at the lowers settings. The defrost light doesn't come on until that setting also, so definantly no power. When turned...

I'm assuming you mean the fan only works on high. If that's the case the blower motor resistor is bad. When the fan switch is on high it puts a full 12Volts to the blower motor. When you have the switch in any other possition, the voltage is routed through the resistor and reduced thus making the motor run slower.

Blower for ac/heat only work on lower 3 levels.

Check the blower motor resitor. Use a 12v test light at the switch and notice the bulb brightness change as you switch settings.. Probably have a bad blower resiter.
