My ECU is flashing a code 8. It means a - "TDC Sensor (Top Dead Center) defective circuit or unplugged / defective sensor."

Where is this? My car's in limp mode and it sux. How can I fix it?

 

Code 8 - Top Dead Center Sensor

It's the second sensor in the dist. It can also be located on the camshaft of DOHC engines. It determines the injection timming for each cylinder, also used to detect engine speed (rpm) to read the basic discharge duration, for different operating conditions.

If the dist. base bearing starts failing, it will heat the sensor(s) up, destroying the magnetism thus causing a code(s). It will lose 10% of it's strenght, each time it is heated up, to a 170 degrees plus.

In most cases, replacing the distributor is the only alternative. Especially if the bearing has failed.
Honda does don't stock the bearing, but other after-market compaines are said to have one.

If you have problems starting the engine, or drivability after the install check your cam aligment. The seizing bearing might have caused it to jump a tooth/notch or two. From the extra drag due to the bearing failing.

 

Wow, nice post and very informative! BTW: My distributor bearing IS failing. It has heated up the shaft so much that the rotor melted! So I guess that's it! Wel, maybe I'll be just driving it in limp mode until I get that SOHC ZC swap in!

 

i got the same cel today when i was going to work.

i have a dohc zc and the car will not start now. it was fine yesterday and this morning a code 8 and no start. i ordered a dizzy from distributor king and it should be here tomorrow. i hope this fixes my problems.

i have a b18a1 with a pr4 and i am getting code 8 ... is this the same?\

if so ... TDC... does this mean ignition timing or all timing is off?

thanks

All codes are there^^^

And BTW I started my car this morning and no code. I guess it cooled down and that helped.
