Default Honda 98 Civic (Needs CPS)

Hey All

Lovingly used but tired Honda Civic 1998 4 door. It most likely needs the CPS reinstalled. It cuts out in traffic, has very little pep, and the RPMS fluctuate. It also has hard start/stall issues. The code coming from the OBD scan is P0335 as well as P0705.

My uncle has agreed to help me and my friend put a new CPS in, and they are about 30 bucks, but the local advance auto (And this is a very rural town) says they do not know whats in there.

Can anyone help me before we rip the car apart, perhaps a honda mech or ...

I can provide any info needed

thanks again, I think once the CPS is replaced she will have a new lease on life.

Unplug ECU connector C, and use a multimeter to measure resistance across pins C8 and C9 and to test for a short in the pin C8 and C9 wires.

The other code (which you likely typed incorrectly) is an automatic transmission code.

If the CKP (CPS) fails the ohm test, you would replace the whole distributor. The sensors inside the distributor are not considered field-replaceable and generally not sold separately.

After replacing distributor you need to set the timing with a timing light.

Also the #1 rule of rebuilt parts is NEVER turn in your "core" part until after the new one is on the car and working.

On the 96-00 I think there is a crank sensor on the crank snout. That is the sensor you are looking at in your "shopping cart" The CYP sensor is in the distributor and like mk378 said it's not sold separately or considered replaceable outside of a new distributor.

FYI - Code P0335 is for the distributor CKP sensor circuit not the CYP sensor circuit. And it's currently unclear whether the CKP sensor is bad.

TomCat, the sensor you are referring to is actually the CKF (Crankshaft Fluctuation Sensor) and this sensor does not correspond to the code that the OP has given. Incidentally, a failure of this sensor WILL cause a reduced engine redline... some might call this limp mode or safe mode.

Thank you guys. It was my understanding the CKP/CYP/TDC sensor is the same sensor in the distributor. I did a failed attempt to point out to the OP that the sensor he was indicating isn't that sensor in question but the one on the crank snout which I couldn't remember the name off the top of my head. Kindly indicated as the CKF sensor and doesn't actually tell the ECU the precise position of the crank as much as speed revolutions to catch variations (skipped tooth).

OP as these two gentleman pointed out, the CKF sensor in your shopping cart isn't the one causing your code.

Hey guys

its been a busy few days, I DID NOT buy the sensor. The car is still running. I took it to Portland Maine this weekend. I live in Rochester NH (About a hour away). On the turnpike the car started "lurching" and no matter how hard I pressed the accelerator it would not go above 45, it dropped to 40 and then magically it went back to normal. It reminded me of the old cars when we would put bad gas in them and have to clean the carbs out. The car also shows signs of loss of power during the shifting process and sometimes it will still stall.

The important thing for me right now is its running. My uncle has said in two weeks if we can get a bead on the problem (which I know you guys here are trying to help with) we will tear into it and try to fix it. He has offered a pickup (5 speed) as a loan if the car fails, and has a car trailer in case it does break down somewhere. So no tow fees and a backup truck keeps me driving it to and from work (Which is about 11 miles one way to the interstate and i work right off of there) . I am limiting all other uses at this time.

I do want to solve this, on my way back from Portland the other night my uncle had me stop by and he pulled the distributor cap off, thinking it might be moisture. The cap was solid, no cracks and no moisture, but it was a guess at least.

I understand now the OHM tests, and also the sensor is not the issue, I am on the same page and appreciate any help. Ill run those tests soon!

Thanks guys

The transmission code can be dealt with later.

There's an enormous amount of background noise in tech threads, but the solution is so close, if I can just get you to listen:

We will be running these tests today! Ill report back soon. I have driven the car over 400 miles since last report. She is still functioning good. The random loss of power is still there and sometimes on the highway she will not go over 40mph. When she cuts out if i give her gas she starts to shut down, and still occasional stalls.




I am super curious to finally fix this gremlin!




WIll report back soon!

Default Re: Honda 98 Civic (Needs CPS)

worked for 4 hours, finally got connector off but lost track of what to do after that, we also tore the door off to see if we could fix the lock switch not working, honestly its not my car and I am tired of dealing with it, Ill drive it until it dies. Then Ill use my uncles truck to finish the deployment.

I am sure for the mechanically minded this is a fast fix, but I stared at that attachment all day today, and I know I am missing something, but then again no one on here could realign a 200 port Cisco switch and power boot an AS400 with SCSI drives for secure configuration, so there is that

Oh well, write back if I missed something

thanks guys, the car is buttoned back up but the tabs on the "Easy to remove" connector is now broke, so I can go downstairs and pull the connector anytime easily once I have CLEAR instructions

The distributor connector is removed in two steps. First lift plastic tab that holds connector onto metal bracket and lift upward. Second, uncouple the connector itself.

However, you should first do the test on the ECU connector not the distributor connector, as mentioned in my post you quoted.
