93 Mazda 626 CEL code?
I checked my car for stored CEL codes and all that I got was an 18 (one
long, 8 short blinks). I cannot find any reference to this code online. Can someone tell me what an "18" means? Car is a 1993 Mazda 626 with V6 engine and auto transmission. |

Are you sure it isn't a code 9, (coolant temp sensor signal out of range)? FWIW, the first thing I thought was that 18 was a fuel mixture type of code, as it is the next number after the famous code 17, but upon checking my sources it doesn't appear... I would double check for a code 9 and if it *is* your code, troubleshoot the ECT sensor/wiring. If the fault is intermittent, verify the wiring from ECM to ECT is OK with ohm meter plus wiggle testing, verify the female terminals in the ECT connector are tight and corrosion free, then replace the ECT sensor; they can experience an intermittent internal open circuit that will set code 9.

We figured out what it was... It was a 10 and an 8. I had forgotten to connect the MAF sensor about a month ago for a few minutes while cleaning my throttle body. Thanks! |

In retrospect, I feel like a dumbass for not thinking of that possibility. It's extremely common for someone to leave the MAF conector off after air filter or throttle service. Those two codes will set within one second of the ignition key being turned to "run". Toyota MDT in MO |
