Error Code P0203: Cylinder 3 Injector Circuit Malfunction

So I jumped in the WJ this arvo and just up the road from home she stopped running. It would start but run very rough and then stop.

Out with WJDiag Pro to discover that I had this error code:

Error Code P0203: Cylinder 3 Injector Circuit Malfunction

I've seen this before on another cylinder and fortunately it was an easy fix last time reseating the injector connector solved the problem, the same thing fixed the problem this time.

So if you experience this, don't panic.

This also relates to P0201, P0202, P0203, P0204, P0205 on the CRD, I'm assuming it'd go up to 206 for the I6 and 208 for an V8
