Hi everyone.
The other day on my way to work my engine management light came on so thought I would have a go at reading the error codes myself following the guide.
It came up with CEL 17 - Vehicle speed sensor
As I was at work and a 30 mile journey home looming, I reset the ecu by pulling the fuse for a few minutes.
Popped it back in, started the car, let it idle until up to temp and set off on my way.
Car ran fine all way home. A few smaller journeys later, so about 50 miles since resetting the ecu, the speedo stopped functioning and a few miles after that the em light came back on again.
Checked the code again and as suspected it came up with the VSS.
After reading up on the fact that it was most likely the speed converter, I removed my intake and had a look for the little black box on top of the gearbox.
I checked the wiring, and visually it looked ok. Wasn't too badly insulated from the elements and no corrosion.
After putting it back together and resetting ecu again, the EM light came on again after a minutes drive.
So the next thing to try was eliminating the converter. Removed the box and reconnected the wires, matching up the colours. For the record I soldered them rather than twist them.
Reset ecu, started her up and it was still the same. CEL 17 - VSS. and no speedo
I left it for a few hours pondering what to do with her next.
The next time I fired her up my battery light stayed on as well as the EM light. Also the car felt very restrictive, hard to describe but spongey throttle? Like when you put a CRZ into eco mode.
Now this was just swapping my cars round on the drive. I did not take it for a drive.
I checked the CEL codes again and this is where I got worried and thought i'd best post up here.
As before, it came up with CEL 17 - VSS, but then to my horror it threw another 4 codes at me!
20 - Electrical load detector (high or low voltage)
41 - Air fuel ratio sensor 1
57 - Camshaft position sensor or Variable valve timing control
65 - Secondary heated o2 sensor 2 heater circuit malfunction
Could this be a case of bad battery that suddenly threw up the extra codes? As in a total coincidence? The Teg is not my daily driver and I have not replaced the battery in the 3 years I've had her.
Sorry for the long windedness of the story. I think that's all the info in there.
Any help would be much appreciated. I can possibly get hold of an OBD2 code reader on Friday to get the full P codes.
Many thanks in advance,
Pete
