Toyota 4WD Surf Owners

Hi Folks,

I was hoping to find a thread with this error code in it but I didn't see anything.

I just put a new 2L-TE in my 92 Surf.
(I pulled the EGR system at the same time).
When I first started it the engine it ran at 3K RPM.
I turned it down, (thinking on it, that may have been a mistake).

I have an error code 13.

Can anyone please give me an idea whether this could be the crank sensor, or if it is a problem of some kind and what I should look for?

I imagine the first thing that will be asked is a question about the timing.
Anything is possible, but, I checked it three times and turned the crank 720 degrees (two full turns CW) and checked it again, I checked it a forth time before installing the cover. (I've been here before).

The pump is set to the proper lines as well.

I should think there is a resistance test I could run on the sensor, I just don't know the drill to do that.
Also, the crank sensor seemed a little less than perfect when I installed it, so I'm not confident it's OK.

Any help is most appreciated.
Thanks in advance, Allen
