My 2002 grand am se it will not pass inspection ,there is no ckeck engine on .my 025 not ready

You did not give enough information about what you did not pass on emissions. Usually it is the co2. If that is the case, it is either the sensors at the catalytic convertor need replacing, or the catalytic converter itself. You can get sensors at the wrecking yard but NOT catalytic converters.

How do I get the service engine soon light to go out

The "Service Engine Soon" comes on when the ECM receives information from the engines sensors that exceeds normal acceptable operating parameters. The ECM will store a code (or codes) indicating which system(s) are out of tolerance and light the "Service Engine Soon" lamp. The technician will read the codes, diagnose and repair the condition(s), and reset the "Service Engine Soon" lamp. The lamp does NOT go out on its own (in most cases), once repairs are made. There is a scan tool that is used to clear the stored codes that allows the lamp to go out. It is therefore possible that you may already have fixed the condition that set your light to on. Or not. The whole purpose of the lamp was to help avoid the kind of "hit and miss" repair methodology that you have employed so far. Many feel the need to try this as they fear the costs of a professional mechanic reading the codes and the cost of repairs. Fortunately, there are less costly options available. Many of the large auto parts chains will read the "Service Engine Soon" codes for you at no cost. They will tell you what codes are present and you can decide if you (or someone you know) can perform repairs or if you need a pro to check things out. They do NOT, normally, perform resets of the lamp as this has potential liability issues for them. If you need the lamp reset after repairs are made, you have two options; pay the pro, or buy a scan tool that has the ability to reset the light. Not all do. The cheaper units are only code READERS. Be careful when you buy. But if you watch for sales, you can usually get a low-cost scan tools that can read and reset codes for around $40.00. Good luck.

My 03 colt check engine light came on mechanic ran diagnostics no errors or problems found light reset then back on a week later any ideas?

This is the problem your mechanic is going by code,code just point you in the direction , Its data, whats the fuel trim? Whats the freeze frame data? These are what you need,The CK ENG LT,looks at rationality,logic,open shorts and ground.You can have a 02 code,but the 02 is responding to the engine,Its data that the mechanic needs to know.

Service engine light

service engine light on Nissan will not damage the car in any manner, however you gas mileage may change slightly. Service engine light can be numerous of issue. Fist I would change the Co2 sensor, 99% that will be the main issue, most people don't realize that unit need to be replace every 50-75k miles. if that does not solve the issue than take it to the dealership and have them plug it into their computer and it will spit out a code so mechanic can narrow drown on what need replacing. Running bad gas or running low octane can also cause the light to come on. Before you change Co2 sensor, go to Mobile, Shells, Speedway, gas stations and put in 93 or highest octane gas and go to Automotive store and pick up a STP fuel injectors cleaner, mix it with full tank of gas and run it til next refill and see if that light goes off, if not than change Co2 sensor. I believe that truck has 2 sensor if it a V6. the sensor located on the exhaust pipe before catalyst converter. its easy to fix and replace if you have the tools. if you don't know where the sensor looks like or located on the car, just get the new parts and look compare the old to the new. they run somewhere around 35-40 bucks each. Co2 sensor measure amount of burned gas telling the computer if its running rich or lean, if the sensor goes bad the computer get trip and the light comes on. good luck!!

I have a 1998 Toyota Avalon XL - the engine sign is on for a while...the mechanic says it will cost $300 - it's the oxygen it right?(He says that after replacing I have to do 50 miles...then...

If the sensor is bad and needs to be replaced, the light needs to be reset at the time of repair.

If your mechanic does not have the equipment to reset the light, he can not accurately diagnose the light either and is likely just guessing.

Find a new mechanic, this guy smells like trouble.

Engine warning light on Mazda MPV 2002

There seem to be 4 sensors along the way in the air intake and emissions system.

My Check Engine light indicated a bad sensor 1, bank 2 code (I think).

I had my mechanic replace the sensor that was indicated as faulty... cost = $191.

Then the Check Engine light came on again (with a different code), and I had to leave the van with him all day.

Cost to replace and install that sensor = $115.

My advice: if the Check Engine light stays on *AND* your vehicle is riding rough, get it fixed.

Otherwise, put a piece of tape over that Check Engine light and save a couple hundred dollars!

Hope this helps, I do trust my mechanic fully.

Sensor Problem

1. bring to mechanic
2. ask the mechanic to adjust the intake from the throttle body (it's like adjusting the istributor cap)
3. adjust until it goes back to normal

had the same problem early march '08

hope it helps.
