Hi. I was given a 1995 Discovery and am trying to bring it back to life. Amongst the problems I have to resolve before I can get it safetied are:
- Code 17 (throttle position sensor) on code readout
- SRS light on
So dealing with these one at a time, is the best way to determine what the TPS issue is to test resistance across the range of the sensor? I think I just turn the sensor by hand and see if the ECU reads the proper variation in resistance? Is that the first step or is there something else/easier I should check first? I have a 4.0 Discovery parts vehicle as well but the sensor for that one unfortunately has a different plug system and I'm loath to start cutting wiring if I'm not even sure it's the sensor that's causing the problem.
SRS light: the vehicle was sitting for maybe 2 years with no battery, and I tried a bad battery before putting a new one in, so it seems like there's a very good chance it's just on due to low cranking voltage. However, a call into the dealer didn't yield a response so I'm not sure they can/will reset the SRS light. I just drove 2.5 hours to a Land Rover guy who claimed to have a computer to reset this, and then couldn't figure out how to interface with my vehicle so that was a frustrating five hours of driving for nothing, apparently. I've read every site I can find about how to find the serial link mating plug, but for the life of me I can't find it in my truck, anywhere. I've looked under the passenger footwell, driver's footwell, behind the glove compartment, under the passenger seat. Nothing. Could it be possible that it was actually just forgotten in my truck? I'd rather not just disconnect the light, but if it comes down to it that's what I'll do.
Thanks for any tips or ideas,
- Andrew.
