My Toyota Corolla AE110 year 1994 if not wrong with 16 valve EFI engine found error 52 after diagnostic jumper test. May I know what might be the problem is and how serious will be the problem cause. Can lead me some step for checking?
DTC 52 is set when ECM detects an open or short in the knock sensor circuit with engine speed between 1200-6000 RPM. Check for open or short in knock sensor circuit, a loose or faulty knock sensor of faulty ECM.

This code is for a knock sensor, before doing anything I would clear the code and test drive then re scan with an OBD11 scanner report back if there is a new code set.

If not wrong my car cannot use any scan tools for scanning.I only found a diagnostic socket in front engine part. Can it be scan using scan tools?

Another thing.I accidentally start the engine when still jumper at the diagnostic port. Will that make any effect to my car ECM?

Leaving the check connector in will not do any harm, do not leave it in there all the time, but for testing it is not a problem.
