Temp. Sensor Question

[stefan]

I've got this fault on my car:

1 Fault Found:
01039 - Coolant Temperature Sensor (G2)
30-10 - Open or Short to Plus - Intermittent

In playing around, i disconnected the coolant sensor and got it to spit out this code too:

1 Fault Found:
17664 - Engine Coolant Temp Sensor (G62): Open or Short to Plus
P1256 - 35-00 - -

It the service manual, these 2 items are almost always mentioned simultaniously, and im just wondering what the difference is between a G2 and a G62 sensor. The G2 fault is reoccuring (the other one i think i triggered) so I have to deal with that soon.

Also, is this the sensor that the glow plugs use to determine how long they stay on? because I dont think mine stay on long enough sometimes.

Thanks!!, Happy Thanksgiving!

Re: Temp. Sensor Question

I don't know if this is the same problem, but I had to replace the engine coolant temp sensor last year on my 01 Jetta 2.0L.

Data from my invoice:
059-919-501-A TEMPSENDER - $ 7.74
N-903-168-02 SEAL - $ 1.82
CVW (Labour) - $132.75

The code scan indicated a fault in the engine coolant temp circuit, and the mechanic traced the problem to the sensor. I don't know what the code was that came up.

Hope that helps.

Re: Temp. Sensor Question

probobly one of the easiest fixes. its literally pop sensor out, pop new one in. took me less than 30 minutes to do on a friends car.
remove the rad fan cover to gain better access to the area, if you dont have small hands (i dont but they are nimble) you can remove you battery to gain a better angle at the area.


edit: this was on a VR6, not sure where its located on the 2L but im sure it cant be too difficult. for the $$$ involved i would take the time and find out the DIY way. its not a technically hard, or tool heavy change

I almost fell out of my chair when I saw the $132 of labor!! My 2003 jetta TDI had the same 1039 fault code. Went to partsource in 17 ave. THey ordered one in over night for like $6 or $7. The only problem is the plastic clip that holds it in. I broke mine taking it out. They are $1 each at VW. Have it on hand first. Didn't even bother draining coolant, I just counted on losing about a cup when I pulled it out. Topped it up after. Total cost about $10 and 15 minutes of time. The most time was used taking the engine cover off and putting it back on. And then VW wonders why we question their labor charges? Just aske them for a quote to change a timing belt.

The most important thing is that I read eslewhere the original ones had black plastic base and were faulty. The new updated one has green plastic base and supposedly solved the flaw. All of the black ones will eventually fail (according to what I read, not stating a fact).

Clearly another case of what should have been a recall but VW is letting owners fix it on their own while they quietly deny any problems with the design.

Don't forget to clear the codes.

$132 in labour?!!? Whoah. As said above, should take all of 5 minutes to do (at least on a 1.8T). I can't see it being that much more complex in a tdi!

If your car is cold. you should be able to do this without losing any coolant (unless you squeeze your hoses). The system is sealed so if you're careful you'll be fine. The 1.8T sensor is on the 'top' of the upper rad hose, so it's really a piece of cake. Not sure where the TDI one is...

Re: Temp. Sensor Question

Yah, that is what I thought too.

I believe the location is the same on all of them. I squeezed and lost about 1/2 cup.

Make sure to get the green one!!!

Re: Temp. Sensor Question

The reason why the cost of doing a simple thing like a coolant temp sensor is so high is that you can't get away from the high overhead of running a dealership. Usually the door rates are between $85-$100 and dealers use a flate rate system for jobs. So, if a jobs book time is 1.5 hours and it takes the tech 1 hour to change you still get dingged with the 1.5. But if it takes the tech 2.0h then it's his / her loss.

Dave,
Sounds like a tough gig. Darned if you do, darned if you don't. If you don't fix it right the first time, the whole company is to blame. Fix it right the first time, then we complain it costs too much.

I don't lower my prices as I am in business to make money but then we expect others to do the things they can't for free. I am as guilty as the next guy for that. Thanks for saying how it really is.

I just hate the bad rap dealerships get. If everyone did their job and did it to the best of their abillity it would make the dealer a great place to go and have their cars serviced. Heck, we might even make a few friends along the way!

And bad parts, nothing like having to do it twice for that reason
