Question about 2006 Jeep Wrangler

2 Answers

My check engine light is on and I had it checked at Auto Zone snf they said it was a AAT sensor. I replaced it with new but the light is still on after disconnecting the battery for 15 minutes. I did check to make sure it was plugged in good and it was. I notice no broken wires. This is a 2006 Jeep Wrangler unlimited with a 4.0 engine.

Let's try this trick. 1- Unplug the sensor. 2- Turn on the engine for 3 minutes. 3- Turn off the engine. 4- Disconnect the negative battery cable. 5- Turn on the ignition key but not at start position. 6- Take the positive battery cable off and hold it to the ground for 30 seconds, then put it back to its original position. 7- Plug back the sensor. 8- Leave negative battery cable off thru a night, if possible. 9- Put the negative battery cable back to its original position when you need the car. 10- After driving for about 1/2 hours, then a next start it will be reset itself.
If it didn't work then bring back to Auto zone to rescan again. to see what error code this time is to determine what to do next.

My malfunction indicator light of my Toyota camry 2000 is blinking and the car cannot accelerate well. my mechanic seems not to understand the problem. what ca I do?

When you said "...indicator light blinking," I assume you mean "check engine" light is on. Procure a check engine code reader and download the trouble code. When you isolate which component the trouble code is talking about, ascertain its not a faulty sensor. Read the code reader instruction and look up "clear trouble code" to turn off the "check engine" light. Replace the sensor first and see if it stops sending the trouble code. If the sensor is still sending a trouble code (check engine lights up again), then replace the component which the sensor is monitoring.

I have a 2002 gmc sierra 1500. My check engine light is on auto zone diagnostic said fuel pressure sensor. I had alternator replaced new last year. I need inspection done now. Can you help me? Travis

Sounds like you need to get the pressure sensor checked out.
If that is the problem, once it is replaced you would have the code cleared and the check engine light should stay off.

Check engine light is on and auto zone says the code calls for new temp. sensor which I replaced and it didnt fix it. It is my daughters car and she is home for the weekend from school. I can't ge

You did not give the year make and model, so I will give a generic comment.
The problem with going to an auto parts store to have the computer checked for codes is they provide that service in hopes of selling you some parts you may or may not need.
I doubt the code actually said to replace the sensor. It probably said the data coming from the sensor was too high or too low.
Depending on what the code number is, you may actually need a new thermostat.
Trouble codes are meant to give the mechanic a place to start testing systems to find the problem.

Check engine light is on took it to auto zone they said it was my egr valve and i replaced it and check engine light still on........ is it any other sensor that, the egr could have trigger

The check engine light will not go out on its own until usually after 20 or so starts.You need to back to Auto zone and have them hook up the analyzer again and clear the codes (they will do this for free). If the problem was your EGR valve, the light will then go out.

My 2004 pontiac vibe check engine light just came on. car has 150,000 miles. what could be the cause?

There are to many things that can cause the check engine light to come on. Best thing to do is to go to Auto Zone and get the Car ecm scanned for the DTC codes which would indicate the issues to why the check engine light is on. It could be as simple as a bad gas cap and needs to be replaced and if that is the case, make sure your get one from the dealer and not a generic gas cap. It could also be a bad O2 sensor and Auto Zone can give you the step by step instructions to replacing the old O2 sensor with a new on with common tools and they do have that part for sale. Good luck and keep me posted, be glad to answer any more questions you may have.

99 jetta 2.0 check engine light. HELP

Replacing brakes will not shut the abs light off. You have either a bad sensor or accumulated dirt on a sensor. There's a sensor for each wheel so you have to either pull a code or visually see which sensor is bad, craced, chiped, etc, then change. As for the CE light, go to auto zone and they'll hook it up and tell you why it's on. You have to use a scanner to find out.

O2 Sensors

Autozone oxygen sensors do not function properly in Toyota vehicles. Just had a Tacoma yesterday with the same issue. New sensors, runs poor, check engine light on. Toyota sensors fixed it right now.
