the cel can take many driving cycles to clear, i never do that. ever.
i pull the dome fuse , and it clear the NVRAM memory in the ECU, and forgets all stored DTCs.
its very very simple design this, you dont have a scan tool but the dome fuse always works, if not then leave the fuse out for 5 full minutes. (caps can take a bit to discharge in side memory bank)
yes ,all DTCs can self clear but there is no reason ever do let that happen, its a waste of human effort. and fuel... big time.
CEL glows., fix cause.
dome fuse out, then back in. (reset)
CEL flashes 12s now.
drive see if CEL fails to hold 12s (12s is happy feet)
on the 96 we know the conditions for 51's (P0400s) but the 1995, im not sure,
i think its hot engine, light cruise.
im not sure a 95 will set 51s, parked gunning the motor., never tied that.
it is very easy to fool, a 10,000 ohm resistor in place of the thermoprobe fools it.
the ECU does not check for a change in temperature there, dumbly, it just goes, gee, is this thing hot NOW. oh, yes it is, pass.
simple and dumb it is and is the most easy to diagnosis. unlike all other types used.
