Top Dead Center SENSOR Replacement.
 

This looks like the first post about this so hooray for me.

If you have a intermittent Top dead center ( TDC ) error code in your ecu, this is what seems to have fixed it for me.

I would rate this about a 4 on a scale of 1-10 for difficulty and a 10 out of 10 on the irriateded almost punching the car o-meter.

Ill add pics later.
First off.

1.Remove the Three bolts holding the upper timing cover on. Trust me, theres three and youll want low profile wrenches and small hands to get to them, ( you cannot reach them from the bottom of the car so dont even bother. )
2. remove the plastic v-tec panel that covers the coil pack wiring.
3. disconnect the individual coils and remove them
4. tie the cruise control cables out of the way, beucase they are pesky
5. unbolt the valve cover, and the fuel injector hold down plate behind the valve cover.
6. clean the valve cover thuroughly so nothing falls into the head.
7. CAREFULLY wiggle then remove the valve cover and cover the valve train with something, i used a t shirt.
8.unplug the TDC sensor connector
9.remove the upper timing belt cover.
10. locate the TDC sensor just under the cam shaft towards the firewall. It is secured with one 10mm bolt. Stuff a rag underneath and around the sensor to prevent dropping the bolt or sensor into the lower timing cover.
unbolt and remove the sensor.
REVERSE THE PROCESS FOR REASSEMBLY.
this took about 2 hours to do and im a fairly competent home honda mechanic.
any questions, feel free to ask me, or i can help you do it if your in so cal.:rockon:

i was told well let me start it off like this i can be driving and then all of a sudden my rpms drop and my car wont move no where there has been times that i have ahd to pull over in the middle of the highway i was told it could be my TDS <------ would you happen to know

THATS IT, its a little bitch and dosent do it all the time, usually just after your driving for a while. Then it cuts out and you can only limp under like 3000 rpm and nothing higher than 30 mph. I had it happen i know what your dealing with.
hit me up if you need help.

am going to change the TDS and the belt like that i wont have to deal with it any more and then sell my car..

if the tdc sensor is crappin out, it will definatly piss you off and make you nervouse to drive the car, once its replaced it drives like normal again. The part was only like 30 bucks, and only too about 2 hours to install. Dont quit on your ride man.

Never that i can have my Boyfriend to do but the thing is waiting on him drives me crazy hes always hooking up someones car or polishing motorcycles, AAhh my kid (car) needs some attention cause its tru driving with the car doing that its a little fustrating

mine did that after i changed my timming belt and water pump and all it was is some fluid from removing the water pump got on it just cleaned it off and hasnt done it since.

if your in socal ill help you replace it... fo free

very good thread thx for the info. car just started crapping out with that TDC intermittent interruption

sorry to hear that, just swap her out and your good to go.

OH people, when yours starts crapin out can you post your mileage im trying to figure out if theres an approximate lifespan for them.

84,xxx

hey, How many wires could you see connected to the TDC sensor?, and did you see a toothed wheel ANYWHERE around/infront of the TDC sensor?
I need this info for stand-alone issues, Thanks :)

My TDC sensor started causing problems at 145K. Thanks for this post. I've had my '01 Civic into my mechanic 4 times for this problem and they never know what to do since the car's only stalled out on me on days that are above 95 degrees and I've been driving the car for at least 30 minutes. Today I've asked them to just go ahead and replace the sensor.

mine gave up at 190k. With a scanner tool, it was able to pin point to that sensor.
