96 accord wont rev over 3k

i have a 96 accord 4 door auto and my engine wont rev pass 3k. i have a P1362- TDC sensor, P0453- EVAP sensor high pressure, and P0720- output speed sensor CKT malfunction codes popping up. im thinking its the TDC sensor, but can it be the speed sensor?? my D4 light is flashing too. any ideas??

Speed sensor could be causing your D4 light, but shouldn't be causing the short revs.

Several people have had the low revs problem...let us know what it was if you fix it, huh?

I had the short revs problem when I would get to 4K on my RPM's and it turned out that I was low on oil. I added 3 quarts (yup, that's how low it was), and low and behold, my car acted normal once again. So, try checking your oil...

yeah, its got plenty of oil. i think i've narrowed it down to my dizzy. i removed the cap and it was filled with oil. the TDC sensor inside is probably fried. now i just gotta find another one. to the junkyard i go.

My 2000 accord did that i changed my distributor and distributor cap and it fixed it.

ok, its not the dizzy.:banghead: crank sensor time. i've gone through all the manuals i've downloaded and i cant seem to find one that shows me where the crank sensor is located, or any sensor for that matter. i heard its somewhere behind the timing belt?? or in the oil pump somewhere?? if someone could link me to a diagram of all the engine sensors that would be great.

oh yeah, update. the D4 light flashing. there are two sensors located on the very tip of the passenger side of the tranny. i guess they monitor the actual tranny speed and tells the tranny computer when to shift. well anyway, i removed both and they looked like they had metal afros!!! alot of metal shavings magnetically attached to the tip of the sensor. im sure this screwed up any signal its supposed to be sending. i used some brake cleaner and cleaned them up and re-installed them. D4 light gone and so is the P0720 and the P0700 codes. pulled the EGR valve out too and cleaned it out also. it was pretty clogged up. that took care of the P1491 code. i had a P0453 code (evaporator system malfunction, faulty fuel pressure sensor) but it seems to have fixed itself.
just have this P1362 code hanging around. i'll keep you guys posted.

all those sensors are located in the distributor tdc and cps and icm and others too probably better to by a reman distributor instead of taking distributor apart takes too much time and if u dont do it right then you will have to buy a new one or reman good luck

someone told me there is one (crank sensor) located in the front of the engine somewhere around the timing belt. i actually found the sensors wire coming out of the bottom of the engine near the timing belt cover toward the firewall. is that the crank sensor harness?? if not, then what is it?? he also said some of them come with the crank sensor down there and some dont. i think this one does. maybe you are talkin about an engine that doesnt. this one is obviously wired for one so im assuming its there. i got a distributer from the junkyard and it didnt fix the problem. i even took a distributer from my friends 97 accord and it still throws the same code and revs to 3000 rpm. it works fine in his car, so its not the dizzy. i cant think of anything else at the moment that it can be but what the P1362 trouble code is telling me. TDC sensor or crank sensor.

heres a link for ur honda service manual download it and research it yourself

i have them downloaded already. i know what it says but it doesnt show me what sensor is down by the crank pulley. something is down there. and i think thats where my problem is. does any of these manuals show you what this harness is thats going to the bottom side of the timing cover?? i've gone through 3 dizzy's and the problem is not there.

i am telling you there is no sensor down there check these links out or better yet go to autozone.com and look up the part and it will tell you where its located

there is no sensor there?? im looking right at the wires for it.. i'll take a pic of it 2mrw and show you. something is there. im sure these wires are attached to something. there are not there just for looks. lets say its not a crank sensor there. then what the hell is it? i find it a little difficult to believe a CRANK sensor would be in the dist. thats attached the CAM shaft.

Oddly enough Honda does put the CKP on the cam...which makes it a CAM position sensor in my book too but I'm no engineer :lol:

I can't find any reference to a position sensor located on the crank, and looking at a few pics of 2.2 cranks there's no sensor ring to exite a position sensor on them...

I'm not sure what the wires you see are for.

Hey according to my info, PO1362 is Top Dead Center sensor, not Crank position sensor....

but they are both in the distributor...I suggest checking your wiring...1362 means no signal.

Man I've been all over the place trying to find a solution to this for you as it keeps coming up from time to time....

All I've learned that I didn't know is that it's the ECU going into safe mode to protect against possible engine damage when it cuts at 3000 like that....and CKP/TDC sensor faults are the most common code associated with it. The most mentions of it were after engine swaps where they were either trying to use the wrong ECU for the motor or screwed up the wiring while putting things back together.

Ones that were unmodified got resolution after replacing the distributor or sensor(s), but many still had the problem after trying all that.

I still suspect it's a wiring issue. If you don't see anything visibly wrong with the wiring I'd get a pinout chart for that ECU and see if there is a signal present at the computer from the CKP and TDC/CYL sensors...

You might also try powering down the ECU to clear the fail safe mode (I don't know the Honda procedure, sorry) and see if the problem is gone until/unless the code sets again....

ok. i found out from my local dealership that this not the original motor that came with the car. surprise surprise.:shakehead well, we know its not a dizzy probelm, so we can move on from there. how can you tell what engine goes with what ECU? and i was thinking last night, the 3000 rev limit is caused by the ECU shutting down the ignition coil right?? correct me if im wrong. what if i used an external coil to provide the spark. would that work? i know a lot of guys that go external with their coils on boosted setups. i got tons of coils layin around, or is there a hoda secific external coil for these cars, because im sure when i disconnect the plugs from the OEM coil, the ECU is gonna have a s--tfit. can i just leave it plug in and use a regular external coil? i'll post some pics of what i got.

i dont know if these wires were hacked by the factory, or after the motor swap. thick gray with pink stripe wire with the grounded wire goint to a orange with black stripe wire. i found two wires the with the same color code like this.

here are some pics of the elusive wires going to the bottom back side if the timing belt cover, still dont know what its for or what its connected to.

RPM limiter is done by way of fuel cut (injector pulses cancelled)...otherwise if done by cutting spark it would backfire when it came back in....I don't think that will work.

I still think getting a pinout chart and tracing your CYL/TDC sensor's signal all the way back to the ECM will show you the light...

i'm having a hard time finding a real good one, but if you go to the library they sometimes will have access to Chilton's or Mitchell On-Demand and you can look it up there, and print the chart...the good ones not only tell what the pins are for but what the voltage/reading should be when it's running, etc...

if im not mistaken judging by your vin this car is a 97

if im not mistaken judging by your vin this car is a 97

production dates 1-6/96 = 1996. production dates 7-12/96 = 97. plus the title says 1996.

I have a 91 accord that did the same thing. The tdc sensor was built in the distributor. If you find its not a short or anything electrical you might try the distributor.

no if you look at the title correctly it will say year first sold then it will say the model year okay i used to work in a shop and it is imperitive that you get the year right because there might be one slight little change in wiring or how do you know there isnt a recall on this car for this prob did ya check that

the first post on this page starts with me sayin the dealership told me this is not the engine that came with this car. i brought it there because of the free warranty work thats done on this year car with this amount of mileage on it. warranty is void because of the motor swap.

look what i found!! the sensor that doesnt exist.

i'll give you 2 guesses to where its located.

distributor?? no

down by the crank?? ding ding ding!!

that plug looks kinda familiar..

oh yeah, it looks just like this one..

DUDE AF IS HERE TO HELP PEOPLE WITH PROBLEMS NOT PROMOTE SMART@SSES SO IF YOU KNOW WHAT YOU ARE DOING THEN WHY ARE YOU HERE GO SPEND YOUR MONEY AND FIX IT BECAUSE YOU ARE REALLY STARTING TO ANNOY ME AND PROBABLY A FEW OTHER PEOPLE SO YEAH YOU KNOW SO MUCH SO GO FIX IT INSTEAD OF TRYING TO PROVE SOMETHING HERE WHICH YOU AINT AND WONT :slap:

dude, go play in traffic. its people like YOU that give forums like these a bad name by giving out misinformation. :shakehead i tried to tell you there was crank sensor there and YOU made it look like i was the idiot that didnt know what i was talking about.:nono: i think its pretty ignorant to say nothing is there after i post pics of a 4 wire harness going to supposidly nothing. maybe you should have taken your own advice and looked it up yourself before flapping off at the gums. well here it is on the web site YOU sent me to. now tell me there is no crank sensor there. the only reason you are annoyed by me is because i might have made you look like you dont know what you're talking about. not my fault, thats all on you. i've gotten legit info from plenty other people of this forum that proved useful and i dont see anyone else being annoyed but you. maybe you should apologize and mark this up as a leason learned rather than insulting my intelligence, AGAIN, and for the record, i'd much rather be a SMART @SS than a DUMB @SS. thanks for you help anyways.
