ECU code problem
 

my ls swap is throwing the "cyp" code.I looked it up and all it says is a bad sensor,but it dont say which one.I need to figure this out,any suggestions?

Re: ECU code problem
 

how are you reading these codes?

Re: ECU code problem
 

CYP Sensor (Cylinder)
defective circuit or unplugged / defective sensor

Check it out. If its ok, check your timing, and make sure you dont have your air intake sensor and IACV mixed up.

thats the the code,thanks ill try that but i no the timing is perfect so it has to be a sensor

Re: ECU code problem
 

It could be the wiring too, don't assume the sensor is bad yet. With an engine swap I always assume it's the wiring first and troubleshoot from there. You'd do that too if you'd see the swap wiring atrocity that I've seen.

CYP is cylinder 1 position sensor if I remember correctly.
