Lately My check engine light has been turning on randomly while driving. In most cases this has not affected dirvability performance, etc. on rare occasion it will come on when the engine is cold and idling and the engine will shut off.

I just pulled the KOEO and CM codes and got code 54 (ACT greater than self test max of 4.6V) from the stored events.

is it likely that this sensor is failing, or am I dealing with a possible short?

thanks in advance for your input.

I'd try testing the sensor first using the resistance table on this page.
