Either a burnt bulb, or a fuse. The check engine light has nothing to do with the radio.

    Then you either have a bad bulb, or there is no signal going to it from the PCM. Pull the cluster out, and check the bulb. Many people take them out, or let them burn too long, and they need replacing.

    The bulb that lights up for the MIL.

MIL/Check Engine Light will not come on during start up to pass smog 2000 Ford Mustang


There should be a 10amp fuse in the fuse box for the instrument panel that powers the light. The light is grounded by the computer.
Have you checked the fuses in the passenger compartment ?

I HAVE A 97 PLYMOUTH NEON,WHAT IS THE DRIVE CYCLE?


A drive cycle is a test that the on board computer performs while you drive the car to prove out all the systems on the car that control tailpipe emissions, if it finds a problem it will trigger a check engine light and and the drive cycle will not complete. The correct name of this is the "OBD2 ELECTRONIC ENGINE CONTROL DRIVE CYCLE TEST". "OBD2" is short for On Board Diagnostics generation 2. The test is just driving the car at various speeds, stop and go traffic and idle time, make sure you have at least 5 gallons of gas in the tank as well. Many folks disconnect the battery to clear a Check Engine light when a smog is due, this resets the computer (known as the PCM) and then you must complete a OBD2 drive cycle, which of course will turn the Check Engine light back on.

The person running the test is an idiot. The OBDII test instrument is not capable of determining if there is a warning lamp failure. It is probably guessing based on voltage level, but lamp resistance does normally vary. The test is supposed to be done visually. Take it to someone else, and they will probably be more competent and pass your car.

Hello
Does the light ever come on while you are driving the vehicle? It is possible that the vehicle does not trigger the code on the key cycle when vehicle is connected to the OBDII scan tool (a cycle is the time from when a vehicle is started to the time the vehicle is turned off) you should however most of the time be able to check a vehicles trouble code history to see what may be turning the light on
Good luck

Failed CA smog test "MIL/Check Engine Light", computer data wiped


No this is not right. If you remove the battery everything resets anyways. If they are talking about relearn procedure, it should only require 50 miles. But if the light is on than either they did something wrong, created another problem, or there was already another one existing. Have the code read and let me know what it is. I'm in Ca too and used to prep european cars for smog, so I do know what I'm looking for. How did the rest do? What were the readings(if possible)?

whoever installed the egr valve, if it wasnt you, just cleared the engine codes, thus giving you this problem once again. Get it scanned at autozone, and go from there.

Prerunner wont pass smog due to engine service light


Not positive on this so consider only. The o2 sensor is what actually tells everything else what is going on with emmission and everything else adjusts to what info it relays. The o2 is also subjected to extreme temps and cooling cycles. So, instead of spending money on no answer diagnostism give replacement of o3 sensor so consideratio. If you choose to replace, wd40 and let exhaust cool down. Good Luck.
