Yes, it has temp sensor on EGR. I disconnected battery to allow code to clear. While battery disconnected I unplugged the connector to the EGR temp sensor. Hooked battery back up and check engine light right back on again. No change.
That is why I was wondering what could possibly trigger an ECU from a '93 to give a code 53 if it is on a '95 car. Could it be the IAT?
It is Fed (not calif spec) -- both car and ECU.
It seems strange to me that the '93 ECU would have something to trigger code 53 if it was in a '95 car -- were they programming for the future back in '93? Ha.
So, I wonder, is there any other thing, besides the EGR that would cause code 53 on that older Fed ECU. If the engine is running good then the ECU is good, right? I mean, if the ECU was corrupted or capacitor went bad then it would not run good right?
