SOURCE: 97 Dodge Ram Pick up cranks ok engine won't run

try checking all the ground circuits comming out of the PCM. and its also not common for a ground driver in the PCM to fail on dodges. also i have seen crankshaft sensors short out and take out pcm communication. so i would start by unplugging any sensor that runs off the 5v supply until the pcm wil talk to the scanner. if you unplug a sensor and communication returns to scanner then replace the sensor. and dont forget to check for good power and ground at the data link conector and PCM

lrb2199: What this shop has suggested in terms of replacement is pretty much the norm.
1st, if the timing belt lets go or if it jumps time you are going to be hocking the kids to pay for the repairs.
You are looking at a Diesel engine which gets a little on the toasty side to begin with. The motor oil sometimes, depending on the selection may not be too kind on the oil seals.
When you are replacing the timing belt, there is not much more effort involved to remove the front crank and cam seals and replace them with new ones because you are right there! It's a matter of sliding a gear off or unbolting a gear to gain access to a seal.
As for the Water pump, Water pumps don't last for ever and will start to seep through what is referred to as the "WEEP" hole.
If the seal fails, antifreeze will leak onto the timing belt. Antifreeze is a very slippery substance and can potentially cause the engine to jump time. So, you have a water pump that is 9 years old and HOW MANY MILES ON IT? Personally, I would suggest putting another one on. Thermostats also have a limited service life. The part is not that expensive and with the repairs being what they are, often shops throw the labor in on replacing some parts such as thermostats if they are not a big deal. Main drive belts, again, it is a wear item, it could be well worn, possibly may have another 5,000 miles on it, but you have the opportunity to have a new one installed for just the cost of the part rather than pay labor 6 months down the road. The valve cover has to be removed to access the timing belt on some engines because of the way they are configured. Again, the part may not be that expensive, and the opportunity is there to do it while the timing belt is being replaced.
OR, the costs are nominal. Valve cover gaskets on the turbo diesel VW's do start to leak, so take advantage of the opportunity.
I can understand exactly where you are coming from because it is frightening sometimes to hear people tell their stories about what they had to pay for repair on their cars.
Brake shops as an example (NOT ALL OF THEM) seem to be notorious for selling expensive work which may not really need to be done. Example: I have been in business for 28 going on 29 years. I do not sell calipers, rotors, brake master cylinders and other costly items on the majority of the brake work which comes through my shop. WHY? Because they do not need those parts!
I had a customer who learned the hard way. We had given him a quote for brakes. In this case he did need rotors on his Mercedes.
WE use "ATE" rotors and "TEXTAR" pads which are original equipment parts. They cost a little bit more, but I don't have comebacks (complaints). The husband had to leave town and the wife thought we were too high so she called one of the national chains brake shops. They suckered her in at a price over a hundred dollars lower than mine. When she left their establishment her repair bill was a little over a thousand dollars more than my quote.
They sold her calipers, rotors, brake master, system flush, and a hot wax enema! I don't see how they can get away with things like that? I know for a FACT what that car needed because the car has been in here for regular service for over four years. His wife just thought she could save some money! I guess she did HUH?
Anyway, it sounds like your guy is on the up and up.
Got any more questions? I'll be happy to answer them.
Good Luck

2005 vw jetta 2.0L 4cyl bbw engine code: need timing belt set up/marks


Here are a few diagrams to line up crank and cam, note there is a tool used with valve cover removed and slides into rear of cam to lock into place but as long as you hold it in the correct location with a wrench you will be okay and the crank you will need to put lower cover on and use lower pulley to line marks up and then double check the mark at the rear on the transmission, there are two diagrams i sent one is for automatic transmission and the other manual , i labeled them, the tensoiner, i assume you know how that must be done , if not let me know, the pointer must be in the right location. after timing belt is on you will spin crank two complete times and check the alignment marks if they are off try again. note you must not assume it is lined up spin crank to check.12_25_2012_7_59_29_pm.png12_25_2012_7_59_40_pm.png12_25_2012_7_59_50_pm.png12_25_2012_8_00_03_pm.png12_25_2012_8_00_16_pm.png

How to remove a water pump on a 2004 jetta 2.0


I have a 2004 Jetta 2.0 BBW engine with 111,000 mi and I should be thinking about changing both the pump & timing belt because they're in the same location. I did change them on my 1991 Accord after the bearing in the pump went. Thank goodness the belt didn't break and mess up the valves.These two engines are very similar (one's a rice burner the other sauerkraut) So here's the best thing that I can tell you, buy a Hayes Repair Manual (VW 1999-2005). Follow the sections on water pump and timing cover removal. The mechanical part of the work is easy, it's the braineac thing of getting TopDeadCenter, the belt and all the pulleys in the proper alignment, if not, kerbang. You will need a special tool to line up the camshaft at TDC( shows it in the manual and you might be able to rent one) I used a steel straight edge on my Accord. It's not as scary as it sounds. You can do it if you check twice at each step and do it right once. PS it's cheaper to replace any parts that look worn then to tear it all apart again. Hope this helps and saves you $500 or $600 at a shop.

P0335 - Crankshaft Position Sensor A Circuit Malfunction

The crankshaft position sensor (CKP) measures crankshaft location and relays this information to the PCM (Powertrain Control Module). Depending on the vehicle, the PCM uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing. The CKP sensor is stationary and works in harmony with a reluctor ring (or toothed ring) that is attached to the crankshaft. As this reluctor ring passes in front of the CKP sensor, the magnetic field created by the CKP sensor is interrupted and this creates a square wave voltage signal that the PCM interprets as crankshaft position. If the PCM detects that there are no crankshaft pulses or if it sees a problem with the pulses on the output circuit, P0335 will set.

Symptoms:
NOTE: If the crank sensor is used only for misfire detection and NOT spark timing (this varies with the vehicle), the vehicle should start and run with MIL (Malfunction indicator lamp) illumination. Also, some vehicles require several key cycles to illuminate the MIL. If this is the case, there may be no MIL illumination until the problem often enough over time. If the crank sensor is used for BOTH misfire detection and spark timing, the vehicle may or may not start. Symptoms may include:
* Vehicle may not start (see above)
* Vehicle may run rough or misfire
* MIL illumination

Causes: A P0335 "check engine light" code could be caused by:
* Damaged CKP sensor connector
* Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway)
* Sensor output open
* Sensor output shorted to ground
* Sensor output shorted to voltage
* Failed crank sensor
* Broken timing belt
* Failed PCM

Possible Solutions:
1. Using a scan tool, check if, when engine is running or cranking, that there is an RPM signal.
2. If there is no RPM reading, then visually inspect the crank sensor and connector for any damage and repair as necessary. If there is no visible damage, and you have access to a scope, you could check the CKP 5 Volt square wave pattern. If you do not, then, obtain a resistance reading of your crank sensor from a repair manual. (There are so many different types of crank sensors that there's no way to put here which resistance reading is correct). Then check the resistance of the CKP sensor by disconnecting the sensor and measuring resistance of the sensor. (It is best to check resistance readings from the PCM connector. This rules out any wiring problems from the start. But it does require some mechanical skill and shouldn't be performed if you\'re not familiar with automobile electrical systems). Is the sensor within resistance specs?
3. If not, replace the CKP sensor. If so, recheck resistance reading from the PCM connector. Is the reading still okay?
4. If not, repair open or short in the wiring to the crank sensor and re-check. If the reading is okay, the problem is intermittent or the PCM may be at fault. Try reconnecting and checking for RPM signal again. If there is now an RPM signal, wiggle test the wiring harness to try and induce the fault.

This code is basically identical to P0385. This code P0335 refers to Crankshaft Posistion Sensor "A", whereas P0385 refers to Crankshaft Position Sensor "B". Other crank sensor codes include P0016, P0017, P0018, P0019, P0335, P0336, P0337, P0338, P0339, P0385, P0386, P0387, P0388, and P0389.

Test it and keep us updated.

P1372
- Segment Time Incorrect


This engine is very sensitive to overheating and will easily warp the cylinder head. On the other hand, all the performance symptoms as well as the misfire code can be caused by a faulty crank sensor.

This leaves you at a crossroads as to how to diagnose. You could replace the crank sensor and see what happens. Or you could do a compression test to get an idea of the general health of the engine.

As for the lack of heat, you may have an air pocket in the cooling system or it may not be completely repaired. If, for example, the thermostat were stuck shut causing the pressure to build and crack your radiator, you'd still have the problem that you have no coolant flow, resulting in no heat.

Unfortunately, considering the overheating, my inclination is that you're more likely to need a cylinder head than any of the minor repairs I've suggested. But the only way to find out is to check the cooling system, compression, and crank sensor.


Hope helps.

Hello - I just bought a 2004 Jetta - day one - mil light came on. Car runs fine. What could it be? 2 mechanics checked the car over before I bought it and carfax said it was one owner no problems.


Have VW check it out. I had just got my 04 GLI with 70,000 miles when the light came on. The thermostat triggered the light and so I had the whole timing belt, thermostat, and water pump service. Worth the money.
