P0336
 

My gfs 2002 lx civic has a plm...It sometimes will stall when she is slowing down to a stop. I changed out the bosch spark plugs thinking it would help, before we had the code read, and it didn't. So she got it read today and got that p0336....she talked to her friend who said he thinks the mechanic might have sabotaged it when he was doing the timing belt ( about 5,000 miles ago) so the Ckp sensor would break and make some extra cash. I trust the guy and doubt he would do that. Does this sound plausible?

I know it is a civic question but I didn't want to sign up for a civic forum then post once and be gone. I thought maybe someone here could help. Thanks guys.

It could have a broken wire, do you have a digital camera. Can you see the wire for the sensor, can you trace it to a connector. Do you know which of the CKP wires go to the ECU to do a continuity test with an ohm meter.

I have seen the wire chaffing on the alternator belt until it broke. Not sure if that was a Civic, but a Honda it was.

RE: P0336
 

The crank sensor is down on the oil pump, so he probablywould have unplugged it when doing the timing belt. Maybe he simply didn't plug it back tightly & it came loose. (Maybe just careless &not 'sabotage')

RE: P0336
 

Dang! She had him order it and its special order so no refund. I wonder if she can call him tmw to have him cancel it and then verify if it is just not properly plugged in. Is it something I can can look at myself? Would I have to remove the crank shaft pulley bolt?

Thanks you guys for your responses!

RE: P0336
 

It's mounted on the oil pump. If you look straight in thru the wheel well, it's about 3 oclock alongside the crank pulley. I don't know for sure, but it looks like the sensor would be covered up by the lower timing cover. Maybe the wire & plug poke out the side of that cover where you can check them?.

RE: P0336
 

sensor is located inside t-belt cover to replace you got to remove the lower t-belt cover
but you need to diagnose first
disconnect the connector has 3 wires, put the key on ,hook up a volt meter between yellow/black and body ground there should be about 12 v. if not there is an issue on that wire from main relay to cps.

if you got battery voltage,

chk voltage at blue wire and body ground should be 5 volts,

chk voltage between yellow/ black and brown/yellow . should be battery voltage

if all 3 tests are ok , you need a new CPS ,, if 1 of the test is not ok, you got wiring issues or bad ground or possibly ecm/pcm issues

do these tests and let us know

but first i would do a visual inspection of the wiring, surroundind area , loose connector etc etc .

Update: She took the car to the mechanic and he found that the plug had shorted out and for some reason there was water in there. This happened b/c some how the grommet corroded and allowed water to get inside. Just thought i'd update in case anyone ever runs into this.

RE: P0336
 

personally, i feel it was messed up. i'm glad it's fixed though.

that sensor needs to be removed to remove the timing belt. if he didn't secure the connector properly on reinstallation or didn't bolt down the sensor correctly...honda uses water proof connectors. the only way water gets in is if it's accidentally put in.

RE: P0336
 

Your the second person to say that. So the water probably got put in there when the timing belt was done? Maybe that grommet thing was not put in securely?

RE: P0336
 

well, assuming the water pump was changed he could have let all the coolant flow right down into it since the water pump is directly above it. either than or not securely connected. order the sensor, reconnect it, charge you $$ and call it a day.

or

it could be a coincidence. you said you trust the guy, so, if you trust him don't tarnish your idea of him! https://www.hondaaccordforum.com/image/s4.gif

RE: P0336
 

It just kind of got me thinking. Maybe he made a mistake and didn't know? I don't know if this means anything, but she hosed her engine down a few months ago.

RE: P0336
 

first off , sorry for your dilemma .. but i really doubt the the mechanic that replaced the timing belt would think so far ahead as to purposely damage anything so he could make extra money especially if it was done 5000 miles ago,, and also especially if you trust the guy ,,

secondly it is possible like hondatechav6 said that while replacing the water pump a lot of coolant comes out of the block gushing down and could have settled in the connector ( no malicious act by the tech )

but it is also possible, if it was only water , that it could have got in there when the engine was washed by your girlfriend or while driving going through water puddles

RE: P0336
 

Woot! Thanks for that desert. Your post will help ease my gfs mind. A friend of her has put it in her head that she was taken advantage of and I kept trying to tell her that it doesn't sound likely.

RE: P0336
 

I'm having problems reading this thread, what do these abbreviations (words?) stand for?

gfs
plm
Ckp
tmw
b/c

thanks

RE: P0336
 

LOL LOL. can't say that i blame you,, that's 1 way to save space eh?? :D

gfs= girlfriend's ...plm= problem ,,,cpk,,= crank positon sensor...tmw= tomorrow b/c= because

at least that's the way i interpetedd it ..;)
