m52 obd2 - limp mode

[e30forlife]

I've got 12 codes being pulled right now...

Most are sap, rear o2 sensors,exhaust flap and some other ones that should not cause limp mode.

I do have a code for the speed sensor though. I've read a lot about this but can't get a good grasp. Would this cause limp mode?

If I need to post all my codes I can pull them real quick.

PayPal bonus!!!

I have the stupid VSS code that's making my car not rev past 5200ish

The car is a 91 318i with a m52 obd2 setup.

I keep reading about pin 9 on x20 is what I should wire pin 14 on chassis side. I cut a e36 chassis side plug off a donor car and wired it into my e30 chassis side. I only have 2 wires left on the chassis side that are not being used. A black/white one and a yellow/green I belive.

On the chassis plug to the e36 x20 plug pin #9 is not being used nor 14!!

Crisp $20 dollar bill for who helps me fix this issue :)
