I hooked up my 2004 Honda Civic LX to a diagnostics mechanism and it returned with the code for Crankshaft Position Sensor. About a month ago we had our water pump and timing belt replaced by an auto shop. We also have oil leaking from engine, I was told we need to replace the gasket. Could any of these things be the cause of sensor going out? If so which one? Does sensor tie in with water pump or timing belt? Is shop responsible to fix sensor?

So you got a P0335 code?

Probably not a coincidence that a shop did your timing belt recently, but you can give them the benefit of the doubt if you like.

If your timing is off you may be doing damage to your engine so be very careful, as in, don't drive it or start the engine until you figure it out. Tow it to the shop and verify that the timing has not skipped a tooth or two. If it is off, the shop had better fix it, no charge, since they clearly did not do it properly. It could be that they did in fact do it properly but you now have a faulty tensioner, causing slack in the belt, which can cause the belt to skip teeth.

Do you know if you got the tensioner changed with the belt?

How soon after the repair did the CEL come on?

Do you notice any problems reaching higher speeds or any abnormal engine noise?

See this thread for the CPS location

As for the oil leak, what gasket is it leaking from? Is it from near the timing belt area? This is the cam shaft seal. They should have done this when they did the belt! OR, is it coming from the valve cover (top of the engine)? Easy fix, but the shop should do it since they would have had to take the valve cover off for the timing belt change!

timing kit and new water pump were things that were changed. The shop fixed the car before christmas and CEL came on 3 days ago. If I drive past 60 mph then car begins to jerk back more. When I have vehicle in park and hit the gas pedal the rpm reaches between 3 and 4 and begins stuttering and doesnt exceed past that. No abnormal engine noise.

What's the code?

Is there liquid in the connector? Corroded terminals?

P0335, I changed CPS and problem still exists. Cleaning CPS terminals now.

define "the"

which gasket are you/they talking about?

and why was it not replaced while they had the engine half torn apart?

valve cover gasket. i went to shop to tell him im having problems with CPS and if it had anything to do with them changing timing belt and water pump and he said no, that the CPS' go out alot. They were the last ones to mess with valve cover cause you need to take that off to get to timing belt, so I'm wondering if they caused this leak or if they didnt then why didnt they mention that we had a leak? Its a pretty good leak and they were in there 45 days ago. it's frustrating cause I changed the CPS already and not only is CEL still on but problem still exits with car jerking back every so often. Its weird cause it'll drive fine for awhile then jerk (stall.) Someone mention maybe its fuel pump

where is the leak coming from?

are you sure its coming from the valve cover gasket?

where are you seeing the oil?

is it leaking in the timing belt area?

you are supposed to use silicone on the corners of that gasket when you install it, perhaps they did not,

crankshaft end seal maybe?

have you checked your timing marks? do they line up? has the belt jumped a tooth?

leak looks like its coming from valve cover. when i changed CPS there wasn't any oil residue in that area, but there is in front of the engine. gonna get gasket kit and install that next. i dont know how to check timing marks. should i take it back to shop and ask them to check the timing belt to see if it jumped a tooth? should they check it since they are the ones that installed that? why would code p0335 Crankshaft Position Sensor still come on after I replaced it? What else is associated with it that could be causing that code to pop-up?

 
Rep Power: 209

if you have the timing cover off, then check and make sure the timing marks align on the crank and cam (at the same time)

take a GOOD LOOK inside the wire connector that plugs into the crank sensor, is it corroded and rusty?

if so, that could be causing a poor connection and setting the code off

*sigh*, if people actually READ posts... things would be a lot easier.

Simply asking the question again won't get you a different answer. Ok, so you can't rev your engine over 4k? That is a problem. Engine bogging down after 60 mph? GO GET YOUR TIMING CHECKED! Did I say it loud enough? Call the shop, do it yourself, whatever, this should be your #1 at this point!

There are a bunch of DIYs on this forum for timing belts, search "Timing Belt DIY" and LOOK.

jeez.You said it loud enough a few times but saying it louder does not make it correct.We are talking about Honda interference engines.What happens when the timing is a tooth off?The engine's pcm gets a signal saying the timing is off.Then goes into protect mode and will not run.It WILL start.About 5 seconds but no longer.It is usually oil leaking from the crank seal contaminating the sensor and pigtail connector.Spray it with contact or brake cleaner and reset your pcm.Problem solved.

Thread is almost 6 years old.

That's not true. Timing can jump a tooth and the engine will still run. You would notice a loss of power and the MIL will be on but it will run and drive.

I have 5th,7th and 8th generation civics.Have had them all 4 for over 15 years.A few head gaskets quite a few timing belts and alot of extensive work on all of them.Every one of them have at some time jumped time.Every one of them did exactly the same thing.Start and die within 5 seconds.Honda says All obdi 2 civics do that.Engineered to do that.And my 40 years of Honda experience leads me to believe Honda's shop manual.

Well, my 200 years of Honda experience tells me that it will run with timing off a tooth

run poorly, can stall also, but there are some that have experienced it still running (poorly), so it happens.
Anyway, no biggie, we can argue forever and not get a solution here
