Popular OBD-2 H22 CKP Sensor error, Important
Dear Hondata people,
I am having an engine of H22A7 thats located in an European Accord Type-R
Its a serious project and currenlty having an Hondata S300 installed.
H22A7 have all the same sensors that has an OBD-1 car already stock. TDC, CKP and CYP, they all are there, except CKP is on Crankshaft not in distributor, but the teeth count is the same so this shouldnt be an issue.
The problem is that we are having an error code of CKP sensor comming up at all times. Engine seems to work ok. But hard to judge as this error is there all time.
We have checked wires and pins that they goes to sensors and back and they are all functional and wired correctly.
Hondata - have you experienced problem like this and is there a solution. Changing of distributor isnt that easy as H22A7 have a static non rotatable distributor by standart.
Just for reference some picture:

Yes they are elimenated, but we kept the tooth wheel intact for magnetic reading.
We are unable to find a problem, moreever we have built more than 20 Hondata cars, but none OBD-II B H22.
So this is an issue for now. We are in Latvia/Europe and none of Hondata dealers are in logical near distance.
Tried what exactly? And what errors were there?Funnyboy wrote:I tried this.XPEHODATA wrote:1. Try to exchange pins from CKP sensor.
2. Try to exchange pins from CYP and TDC sensors together.
It seems this was not a good idea. I switched the pins back and now the car stalls and runs bad.
Could this joke ruined something?
This joke can't ruined anything.
