Well starting about 2 months ago i threw a cel for #8 tdc error.Since then i have posted on here and tried all the suggestions. I did the reading in the helms manual and tried to trouble shoot and everything passed with flying colors so im completly stumped as to y is still on. Ive even gone so far as to completly eliminate the 2 wires to the tdc censor mainly bacause i wasnt getting any resistance in the 2 (300-700) mili ohms. So today i did more trouble shootine and still have not cleared the cel. Now im not really worried about this but its causeing vtec to not engage and a couple of meets are coming up and i want to see what it will pull previously 156.1 whp with no vtec.Now i have the cam gear set to 3 degrees advanced for jmy cam cause that supposedly the sweet spot for it. Would that cause it to read funny?

Setup
99 ex
y8 block
z6 crank

cam
hondata s300

 

Are you saying that you don't measure proper resistance for the TDC sensor? If so, the fix is to replace the distributor housing.

 

a way which I think may work is to buy a resister of the correct resistance 300-700 ohms and wire it in between the appropriate wires. this is just a suggestion though.

 

no im saying that at the dizzy it was the correct resistence, somewhere in the harness its broken tho so i replaced the wires to try and clear the cel but it still remains

 

So one of the TDC sensor wires from the ECU was broken, right? And you replaced the wires, right? So do both TDC wires now have continuity between the distributor connector and the ECU?

 

ha

 

yes everything is getting the proper resistance and continuity....i even moved the tdc censor closer to the rotor it was pretty far away and i had heard that might be the problem........still a cel

 

Do you know someone who has the same ECU that you do? If so, try swapping in a known good ECU.

 

...or a known good distributor.

 

This is also a good idea.

 

i have like 3 p28s tried the one i was last using before i switched to the itb setup still threw a code and i just switched over everything for my obd1 dizzy to work with obd2b going to try that in and hour

 

must have pinned he dizzy wrong didnt even fire up.....now i need to find how to convert from obd1 to obd2b.....i searched unfortunately everything is for obd2a

 

figured out the pinning of my dizzy got it to start and cel remains

 

Check for damage of the terminals for the TDC sensor wires in the ECU connector and ECU.

 

they are mint now i just need to setup a different ecu for hondata and try that

 

Did your s300 help if not pm me im in WI i'll help you out

 

im not sure what u meant by that i still have to do it... i just dont really want to unsolder the set of pins just to find out that its still there
