I have cel on right now in my car. I'm pretty sure I know what it is, but when I go to use the jumper wire to flash the code, my SRS light just blinks and the CEL light goes off. I'm very puzzled by this. I took it to a dyno shop and they told me that my ECU was looking for a knock sensor that I didn't have and that my TPS was faulty. Well they reprogrammed my ECU without the knock sensor and I got a new TPS. But my CEL is still on. One is there something that I'm doing that is wrong? And two does anyone else have this problem with there hondata. BTW I'm running hondata s100 in a p28.

 

lol the P28 never used a knock sensor. So the ECU shouldn't be searching for one sence it doesn't even know what it is.

 

Right, the guy that program the ECU put the knock sensor on there when I told him not to. I knew something was wrong when I was driving the car and it was hard to drive past 3 grand.

 

With my S300 I can turn it off or on. I also have a P28 so I just have it off. IDK about S100 though.

 

You must connect an s200 module & romeditor to the ecu to check the codes.

 

so this is the only way to check the CEL's?

 

Hey ever figured your problem out I'm having similar issue too
