1995 toyota 4 runner issue

Looking for some help here. I have a 95 4runner a the 3.0 in it I keep getting the check engine light showing code 52 and 14. Anybody know anything about these motors or codes?

I believe 14 is no ignition signal to the ECU, and 52 is the knock sensor. They may or may not be related. I would clear them and drive until the check engine light comes on again and verify both codes are there. Would think if the ignition coil was bad it could definitely cause the engine to knock and trigger the knock sensor code.

You will probably be able to find a bunch of stuff on this on Toyota specific forums. Just type it into Google.
