In all my research it seems there's no definitive answer. My question is: after my MPFI/ZC swap I'm getting a code 4 for Crank Angle Sensor. Am I looking at the dizzy or am I looking at the thing next to the distributor; the exhaust cam angle sensor? Thanks in advance.

*edit 4 usually means either the wiring to the distributor is wrong or the intake cam gear is off a tooth or so

try switching the two cam angle sensor wires

Yeah that's what my friend told me today too... will anything catastrophic happen if I switch B10/B12?

mengy007

just depin on the plug that goes to the distributor it's easier anyhow.

*edit, I've done it before and nothing happened, but try it at your own risk.

yeah i had the same problem
you gotta swap the wires..
I think its the orange/blue one but I will check when I get home
what ECU wiring diagram did you use

why are you gambling with the wires if you have the wire scheme above?

just make sure the orange one is by the empty slot, thats it.

If your timing is right then it has to be the wires unless you have a bad distributor

code 4 is for crank sensor in the distributor - the sensor on the exhaust cam is the Cylinder Position Sensor and if bad (which almost never happens) you will get code 9 - code 4 usually means you have a bad distributor - the picture posted above is one that i came up with and is for the Si/HF distributor connector, not the DOHC ZC - the DOHC ZC distributor connector is the same as the DX/LX/STD connector, like this:

Woops. I removed it so as not to confuse anyone.

i edited my post to show correct connector
