Hi All,

I left work yesterday drove 10mins to supermarket then left, about a min later CEL comes on, I stop let kill the engine, restart, comes on again 10secs later, so I remove the ECU fuse have a look at everything and restart and she is ok all the way home (15mins).

Today start her up she is fine we drive for 20mins, stop the car, when i return 5mins later she throws CEL again. So i read the codes in the car park and I get a :-

#7 TP Sensor (Throttle Position) defective circuit or unplugged/defective sensor.

#9 CYP Sensor (Cylinder) defective circuit or unplugged/defective sensor.

I reset the ECU again and she is again fine for the rest of the day(1hr)

I just wondered what your thoughts are, I dont beat on my car, the oil gets checked religiously and she is serviced as required. I am also mechanically sympathetic.

The last time I thru a CEL it was #8 TDC and that was 2.5 years ago and was my fault as I fitted APEXI Rev/Speed Meter and one of the connections was not to great.

I am unsure where the TP Sensor is, I presume its top of the intake which has a plug going to it? The CYP sensor is in the dizzy I think after using the search

If you all can shed any light I would be grateful, I am not overtly concerned and she is running fine but I want to find out whats making her suddenly throw these CEL's and how they could be connected.


My GF says just drive it till it goes off -

 

bump for CEL 9
I've been looking for info on the CYP Sensor but its been pretty hard to get info on it.

 

I looked for 3 hours last night couldnt find anything, its definitely located in the dizzy for sure. Other than that nothing.

I have read more on CEL 7 but I currently looking for a guide on how to test the TP Sensor, I have a multimeter but all the threads I have read are sketchy to say the least. So any guidance appreciated!

Whats bugging me is the fact that its throwing two errors which kinda doesnt help me narrow anything down and also its throwing them only occasionally!

 

With the TPS you are looking for a smooth transition from 0.49 volts with the throttle closed to 4.5 volts @ WOT. Spikes or dips are bad.

Another bump, thanks for the help

 

Great Stuff thankyou, I presume that is with ignition set to ON position.

 

Any ideas on this? I have driven about 70 miles without it coming on then today it reared its ugly head again. same CEL Codes

 

Have you check the connections for moisture ?

 

im looking right now to get you a document on this i had.

Is this for CEL 7? 9?

I've gotten word from this board that CEL 9 is a sensor within the distributor which may mean I would have to replace the whole distributor housing .... $$$$$$

 

this is for 7. ill check for 9. it got extremely busy at work, i skipped my lunch already.

You most likely need a new distributor. Those with more knowledge than I could probably tell you which part of the distributor you need cuz I didn't need the whole thing. I've heard Honda engines eat distributors.
