CEL Several Check Engine Codes
Posted: Fri Mar 10, 2017 8:06 pm
I decided to finally pull my gauge cluster last night to see if my speedo issues were cable related. When I got it all apart, i noticed that the bulb for the CEL wasn't there. I replaced the bulb, got the speedo cable fixed, put it all back together and started her up.
The good news: speedo fixed
The bad news: CEL was on
I connected the clip to check which code i was getting, expecting it to be 33 for the Vehicle Speed Sensor.
Turns out that there were 5 including the speed sensor
22: Knock Sensor - simple fix, buy a new sensor
23: Air Flow Sensor; abnormal voltage
24: Air Control Valve - iacv?
33: Vehicle Speed Sensor - expected
49: Air Flow Sensor; use of improper air flow sensor
I pulled the fuse for the ECU power and the negative battery terminal and let it sit over night. I was hoping that some of those codes were just old and wouldn't come back.
No luck, the CEL was back on immediately. I drove it to class and back and re checked the codes, everything was back (including the Speed Sensor code)
I'm not sure where to start. The MAF that is in the car if the factory unit AFAIK. The speedo is in working condition again, not sure why the code came back. Do I just need to bite the bullet and get a new MAF, IACV and knock sensors?
Any and all help is greatly appreciated.
TL:DR CEL codes 22, 23, 24, 33, 49..... Help
