A transmission fault code that's not on the list...
Posted: Thu Mar 25, 2021 7:37 pm
Hello all
This is my first post since getting the bongo ('96 RWD 2.5D Auto) - and I just wanted to start by saying a huge thank you to everyone on here for the wealth of information and help that you have posted.
I got my membership straight away, and that's been brilliant with the fact sheets too.
So, first things first - our bongo has spent most of it's time at the garage already (Japtech in Southampton as recommended by the members). It's had it's turbo reconditioned, part of the exhaust replaced, part of the underbody coolant distribution replaced and a reconditioned fuel pump. It's now running OK - but I have the HOLD light flashing. The HOLD light has only been on since it's last visit to the garage to have the fuel pump sorted because it was leaking diesel. So I followed the procedure to read the diagnostic codes and I get:
12 - Throttle Position Sensor
36 - ??
So 12 makes sense - and I was kind of expecting that - seeing as the TPS is attached to the fuel pump. So I'm going to have a go at the contacts for the TPS connector with some contact cleaner and apply a little grease to the outside of the connector to make sure it mates properly. But 36 is a bit of a weird one - I can't find it in any of the transmission fault code lists anywhere. I do have the bongo booked in with AutoTune in Hedge End (who apparently have a fault code reader for the diagnostics port), so I will post back here if I find out what 36 actually means.
But - my question to you guys (and, hopefully, alacrity!) is - what sorts of things should I be checking other than electric plug contacts? Also - I have seen the schematic around the transmission electrical system - but one thing I haven't seen is a physical description of where those connections actually end up... is there such a thing? I don't have a lift or anything like that so it's kinda difficult for me to trace things under the body, and the van has a side conversion which means someone has to hold the driver's seat upright if I want to look under there...
Anyway, thanks in advance for any help/insight
Cheers
Matt
