yblocker Posted August 29, 2014 Share Posted August 29, 2014 CEL comes on with application of 1/4 throttle or so. If driven carefully, it won't come on, but we all know these cars need to be given plenty of gas to keep up with normal traffic.....Then when the key is turned off for about 5 to 10 seconds, a slight click can be heard and then on a re-start the CEL is off. Car is an '87 GL 4WD 5-speed with SPFI. Codes set are 32 (Oxygen sensor or circuit) and 51 (neutral switch). The O2 sensor is new. Where does the one wire leading from it connect to? The code 51 is strange- what neutral switch? Related question: When the green diagnostic connectors are connected, OR the white Read Memory wires aren't connected, the LED flashes 6 short flashes and repeats. What does that indicate? Thanks for any ideas! Quote Link to comment Share on other sites More sharing options...
Cmosfet Posted August 29, 2014 Share Posted August 29, 2014 Hi, someone elae can probably answer better... the o2 sensor connects to the computer under steering column, behind that trim piece . There is a neutral switch in the tranny im pretty sure. Maybe a bad switch or connection. The flashes is the "region" code for the car. Not sure if that is the proper term. Mine flashes 5 times. I think that was US and Canada?. The california ones will flash different. I think its 6 times. I will look it up in the docs when i get home.
