I have a 1997 4dr LX Honda Accord.When i took an emission test the car failed.
When i took to a mechanic he says there is no check engine light in the car.It might have been removed.(I could not see any light for last 1 year)
He suggested that the Check engine light has to be placed first then run for around 100 miles and take an emission test.He says as long as check engine light is not there,car fails in emission test.Is this true,if so how much it would cost to place a check engine light and what will be the time required.If not what is the solution.Please suggest me.
Answer -
I did not realize that by not having a check engine lamp would cause it to fail an inspection, but it does sound reasonable that the emissions test would look for that. The lamp itself should only be a few dollars, but putting it in will be much more, unless you can get to the back of the dash yourself. Since you said that you have not seen the light for the last year, I have to assume that it is just burned out, not missing.
My question: The emission test results say
On-Board Diagnostics Codes Read-2
P0122 - Throttle/PedalPosition Sensor/Switch A circuit ow Input
P0113 - Intake Air Temperature Circuit High Input
Please let me know what shld i do...
Shld i go ahead and get the bulb replaced or get something fixed as per above codes.
I cannot fix it for myself...What do u suggest
Answer -
You are probably going to have to fix it all. The codes are indicating a problem and if you would have had a bulb for your check engine light you would of been alerted to the other problems. You may not have noticed any problem because the internal computer will make adjustments to the engine to allow it to run "properly".
I would take your mechanics suggestion, have the lamp fixed first, but I would think that the computer does not lie and you will need the other work.
AnswerThe Throttle Position Sensor (TPS) is quite expensive ($700+) because you have to buy the entire throttle body and the Intake sensor is about $40. These are dealer items. You should test the parts before you replace them because one may have something to do with the other and you may only need to replace the Air Intake Sensor. There are manuals you can buy at AutoZone or any major auto store for your car and the info would be in there on how to test. If you find the TPS is bad, you may be able to pick one up at a salvage yard.
Sometime you are just better off going to a mechanic and letting the figure out the problem because they have much more advanced diagnostic equipment, it may save more in the long run.
