Most CEL codes you've ever had at once? #5213623 09/15/19 06:08 PM

I don't know if there is a record for it, or if its necessarily something to be proud of, but the most CEL codes I have had at one time was 18.

I'm 17 (about to turn 18 in literally 5 days though) and I got my car on my 16th birthday. Working a minimum wage job I did not have a ton of money to keep aside for large maintenance so there was one period in time where I had 18 codes at once caused by a plugged up VTEC solenoid, bad oil pressure sensor, intermittently working wheel speed sensor, some issue that ultimately caused only my rear brakes to work, a voltage malfunction due to a dying alternator, plus a misfire because I still had the original spark plugs and coil packs.

One piece at a time, all the above have been taken care of thankfully.

Can anyone top me now, is the question.

Not a personal vehicle, but I’ve scanned current bodystyle Volvo XC90 vehicles and routinely found 90+ codes. Gotta love the “odometer tampering” code on a brand new car... crazy

My 97 VW Golf 2.0 had more CEL than it didn't. Almost always MAF sensor or O2 sensor related since it was the advent of OBD2.

I have seen the same on a car with a bad PCM. The tech brought in the printout from the IDS and it was something like 213 codes. Most were C and U codes.

Whenever the battery gets low on any of my early 2000s VWs, I get pretty much every CEL in the book.. Pages on pages..

That doesn't indicate that there are any "true" codes, just a software glitch..

Only a couple. But my VW liked to go all winter with the CEL on, then eventually it'd go out in the summer months.

My new-to-me Camry made it to the inspection station, got my sticker, and set the CEL on the 3 mile drive home. Talk about cutting it close! I spent an hour pulling out the offending part, rapped it on the fender and told it to behave, and it's been fine ever since.
