This morning I noticed my check engine light and slip indicator light were on and my 4 Lo indicator light was flashing. An OBD 2 reader that I borrowed at the local auto parts store indicated a bad knock sensor. I suspected a mouse had chewed through the wires because I have been dealing with rodents camping out in my engine compartment for about a month.

OBD II error code P032D (knock sensor)
