@Ahsai, you're a legend. It's the rear sensor reading a tenth of what it should be. Thanks again.
Does anyone have the DME pin out for 2002 986S manual? It's the multi-plug DME part number 996.618.605.00? I'm trying to diagnose a potentially faulty o2 sensor but I've only got the pin out for the DME with the single 88 pin connector. Any help greatly appreciated! :)
@Ahsai, thanks for your reply. Yes, 12V power to the black wire. I have made a mistake in reading the DME pin 30 to relay, as I was using the 97-99 wiring diagram to figure out the DME and I've actually just been measuring an earth connection 😩 Does anyone have the DME pin out for a 2002 Boxster S? Part number 996.618.605.00?
Hi, We recently got P1276 "Fault Code 22, signal delay time for oxygen sensor ageing, bank 2". The sensor got replaced and within 50 miles it had thrown the same fault code again. I reset it, and it was 100 miles before it tripped the CEL this time. Hooked the Durametric up and went for a drive. There is no resistance showing on the bank 2 plug (see attached image). Everything else was roughly the same for bank 1 and bank 2 as we were driving. I have done a continuity test between DME pin 30 and the oxygen sensor relay pin 87 as per the workshop manual for both sides of the car, with one sensor unplugged each time and it seems OK, it's not an open circuit. There is approx the same resistance in the heater circuit of both pre-cat sensors when measured from the sensor plug. What other resistance in the system looking for? What can I check next? I'd rather eliminate everything before throwing another sensor at it. Thanks in advance!
Hello all, Yesterday the wife took her 986S for a run and the wipers stopped working. When I went to put the car in the garage, they moved to the top of the sweep and stopped, and when I went to turn the car off, they almost went all the way down but not quite. The screen wash isn't working either. Car is a UK RHD 2002 986S. I've checked the 25A fuse and it seems ok, and I've pulled the intermittent relay out and that's made no difference either. I did read on another thread here that the wipers should work on/off without it fitted. I have found loads of info on here about wipers playing up but nothing that answers this specific issue :) Where do I look next? Control stalk? Thanks
