4ws code 20.

Post by **ek9sid** » Mon Sep 19, 2016 5:46 pm

Hi guys. Washed the car at the weekend and as soon as I got in to drive the 4ws light came on. Did the paperclip test which brought codes 20 and 73. Now, from what I've read, 20 is front main steering angle sensor and 73 is a temporary driving thing.

Am I correct? I've tried resetting it to no avail so looking for a front main steering angle sensor (presume that's the one at the steering wheel).

Ahh okay. And so the plot thickens

I didn't do anything with the engine bay though. Do these things just randomly fail with time?

Errrr... hang on.
You have codes 20 and 73 on the 4ws...
Vanzep has posted up codes from the engine ECU...

Exactly what I was thinking, so confused!

The codes suggest some of the sensors are misaligned. You can check this by doing the electronic neutral check as stated in the manual. Though that's for a 4th gen and in not sure if the 5th is the same. I fixed my code 20 by adjusting the main steering angle sensor behind the steering wheel.
