2.0 Camshaft Position Sensor

« on: October 09, 2015, 04:27:59 PM »
My (17 year old) grandson Jesse ran his (lowered) 98 Jetta through ford in a shallow creek (twice) and on the way home it started running bad.  He limped it to my house where it died.  I'm tired of looking at it and want it gone, so I guess I have to fix it.  He and some of his friends "worked" on it and concluded that the engine was blown because it got water in the intake.  I don't know what the actually did to try to "fix" it, but I'm sure I'm dealing more problems than it had to start with.  The only thing I know for sure is that they had removed the air filter element because it was soaked with water and sprayed a bunch of starting fluid in the intake.

So, after it had sat there a few weeks, I went out and got it started . . . had to hold it at about half throttle to get it to start, and it ran like crap . . . but at least it did run.  I plugged in my (super cheap) scanner and got the following codes:

P0171 Volkswagen - System Too Lean Bank 1

P0341 Volkswagen - Camshaft Position Sensor

P1476 Volkswagen - EVAP Control System LDP Malfunction/Insufficient Vacuum

P0137 Volkswagen - O2 Sensor Circuit Low Voltage

P0141 Volkswagen - HO2S12 Sensor Heater Circuit

P0103 Volkswagen - Mass or Volume Air Flow Circuit High Input

P1240 Volkswagen - Injector Circuit Open Cylinder 4

I cleared the codes and spun it over a few times. The CEL came right back on, but the only code it showed then was the camshaft position sensor.

I got a new Mass Air Flow unit off eBay and a Camshaft Position Sensor from Autozone.  The Mass Air Flow unit was easy . . . but where in the heck is the Camshaft sensor?  I've looked all over the internet and it seems that the newer 2.0 sensors are behind the timing belt and the pre-98 are in the distributor.  There is some kind of sensor screwed into the head above the water outlet flange . . . my guess is that might be it, but it doesn't look the one I got from Autozone.  The one they gave me sticks in a hole and has a little flange sticking out with a bolt hold in it.  The sensor in the head appears to be threaded.  Any advice will be greatly appreciated!

It  is behind the cam pully behind the timing belt cover,  you need to loosen the timing belt.  Some skill and a special tool required

I think that if it's a 98 jetta it's an ABA motor so the cam sensor is actually the distributor. It got wet. The connector holds water. Take it all apart and hose it down w wd40

I'm pretty sure it's an ABA.  I'll try flushing it out with WD-40.

Is there a good diagram of vacuum hoses anywhere online?  I've found 3 vacuum hoses not hooked to anything and several more that are rotten and cracking open.

There should be one on the fan shroud of the car. If not I have one I can send you when I get back home.

Update:  I pulled the distributor cap off.  The center pin was burnt and stuck up in the cap.  The rotor button looked like a dog had been chewing on it.  Bought new ones.  The new cap wouldn't clip back on, so I ended up pulling the distributor.  I re-bent the clamps my grandson and his buddies had screwed up when they attempted to "fix" it (I think this also had some relation to the chewed up rotor button).  Got the cap where it would clip back on.  Reinstalled the distributor, lining up everything I had carefully marked.  My feet have not moved from the time I pulled the distributor until I put it back in, but there is no distributor clamp anywhere near this vehicle.  I have the bolt, just no clamp.  I even had Joy come out and look for it.  It's gone.  I closed the hood and it's still sitting there staring at me ever morning when I leave for work and every afternoon when I come home.  Some day I'll go look for the clamp again . . . but not today.

Dang zen, I had one in my camper for you but you left before I could give it to you. I'll put it with the tires and the 2.8 that I need to get to you!

Jesse came over last weekend and searched for the clamp . . . apparently he can see better than me.  He found it.  He also pointed out the diagram of the vacuum hoses near the hood latch.   ::)   After replacing the mass airflow sensor, the coil, distributor cap and rotor button and fixing a few vacuum leaks, it was running better than before he took it four-wheeling.  It sounded great leaving my house and headed to Cleveland!   ;D

Nick - I have installed new headlights and taillights on the S-10.  I've also got all the lug bolts broke loose on Sunny and have two of the wheels off.  Unless something else goes wrong, I'll pick up the tires and engine this weekend.

That's good to hear! Sounds like some level of accomplishment!

Alright, I have tentative plans to go to Stevenson, provided I get permission to take a 2 month old camping in the rain... If not, I'll be around (or at the estate sale that I emailed you about!)

This week has about killed me at work.  For the most part, if I've been at home, I've been asleep.  I forgot this weekend was Stevenson, and I haven't read my email all week . . . so I haven't seen anything on the estate sale.  Maybe I'll leave the tires and engine for one evening next week!   ;D

And it's back.   ::)  Jesse went to visit a friend south of Lafayette and on his way home he collided with massive buck.  A deputy put the deer out of its misery . . . I should do the same for the Jetta, but I'm not up to digging a hole toss it in.  I haven't looked it over in the daylight yet, but I know it's going to need a new hood, grill, headlights, radiator, radiator support, and windshield.
