My 2003 Honda Civic has had issues such as transmission, leaks, and etc. However, when the check engine light came on, it stayed on and there is no flashing. I took it to the repair shop to get it diagnosed, and the issue was the spark plugs and ignition coil. After getting that fixed, I was able to drive my car. A couple of days later, my check engine light is back on. Is the problem something else such as the oxygen sensor?
My car has 216966 miles.
My car has an automatic transmission.
Hi there. Check the computer for any other codes to see if the same code came back or if something else popped up. If the same code came back, then there could be an issue with the wiring to the ignition coil. If there is no issues with the ignition coil, then the wiring harness could have a break or short in it or the crankshaft sensor could be failing. If you are getting a code for a lean or rich condition, then check the following:
