How do you reset the check engine light on a 1989 Mazda rx7 and what caused it to come on in the first place?
goto your local shop, or even better a quick lube (usually dont charge) and get them to run a scan.. it should be an OBD I sensor, not a II.. but any good shop will know that... they will tell you what set the light, and how to fix it, and they can turn the light off.... lataaaaaaaaaa
First you need to determine why the check engine light came on then make appropriate repairs before resetting the check engine light. Take a drive to your local auto parts store and have them check for codes. They will perform this service at no cost to you. Once you have the codes you or your mechanic can determine what the next step should be.
Why would the engine on a Mazda 626 shake on first and reverse and the check engine light come on after a day of driving with a rebuilt motor?
Mazda rx8 there is abnormal noise from engine while starting the engine the noise is like rubbing noise we already check all drive belt and all engine and exhaust bracket and engine and ger support.?
As with any check engine light in an OBDII Vehicle (1996 and newer), use an OBDII scanner to FIRST read your codes and find out why it was on in the first place, then SECOND erase the code using the erase command on the scanner. If you don't fix the problem that caused the light to come on in the first place, it will always return.
First of all you must repair the problem that caused the light to come on in the first place or it will just come back on after being reset. You can try disconnecting the negative battery cable for 5 minutes. This may or may not reset the check engine light. If it does not then you will need to reset it with an OBD2 scan tool.
Assuming you have already fixed the problem that caused the check engine light to come on in the first place, there are a couple ways to turn off the check engine light. The first way, which is the right way, is take it to a mechanic that will use a scanner and clear the codes, or you can simply unhook your battery for a few seconds, and then hook it back up. Either way will…
