WHAT IS THE MEANING OF LACK OF H02S12

Question

BOUGHT 1996 FORD ESCOCT FOUND OUT ENGINE WAS CHANGED WITH 1994 TRYING TO FIGER OUT IF 1996 HAD 2 O2 SENSERS OR EVERY THING IN 1

Answer 1

Hi there,

The 96 had 2 O2 sensors, one before the catalytic converter and one after. The code you have stored would be for the sensor AFTER the converter. It should still have that sensor and unless they had to change the engine computer the code should not appear. Unless there is a problem with the sensor itself.
