A 1994 Mercury Cougar is ( OBD I , EEC IV )
There should be an EEC TEST connection in the engine compartment
on the passenger side below the glove box door is the obd2 connector.
The 1999 Mercury Cougar OBD 2 port is under driver side dash left of steering column
can anyone tell me where to find the OBD2 plug in on a 1999 cougar?
check engine light will be on. visible smoke out tailpipe especially under heavy throttle. use OBD2 to read code, the car will know if its bad
With an OBD2 scan tool. The problem must be repaired or the light will just come back on.
obd2 means on board diagnostics failed not o2 sensor, 1st have to figure out why obd2 failed.
OBD1
No, 1994 is OBD 1
the 1994 Honda accord has an obd2 ecu.
That should be OBD 2
It's too old to have OBDII -_-"
