Golf IV / Jetta IV :: CEL Code For Bad Coolant Temp Sensor?

So my check engine light came on in my 04 jetta sw, and when I had the car read, it gave me a code that tracked down to be a bad coolant temp sensor. I bought the replacement part from my local VW dealership, installed it and the check engine light went away. Now about 2 weeks late it came back on, and I am getting a reading of "Coolant temp sensor high voltage". So it goes from needing replaced, then the replacement is running high voltage?

Golf IV / Jetta IV :: 2001 - Engine Overheating - Coolant Temp Sensor Replacement

My temperature has been randomly dropping, them back to middle, and recently my engine was overheating because I'm guessing the fans didn't turn on, because I'm also guessing, the engine didn't know it was overheating?

Anywho, during my replacement, I made sure to get rid of the pressure, and the car was cold. I tightened the cap again, but when I took the sensor out, all the coolant spewed out.

Now if I understand this correctly, do I have a leak? I figured the leak I had was coming from the temp sensor as it is.

Here's some pictures for those who'd like to see ....

Golf IV / Jetta IV :: 2003 - Code P0118 / Coolant Temp Sensor Replacement?

I recently got the solid check engine light for my 2003 VW Jetta 1.8T GLS. I used a bluetooth OBDII dongle and Torque Pro to pull the code P0118. This seems to coincide with my symptoms:

Car idle at start in park stays around 1100RPM then in reverse it drops to 1000RPM then back into park and it stays around 900RPM and keeps that at idle.

If I start the car then immediately reverse out of my driveway then the car has a very rough idle but if I wait around 5 seconds in park idle then reverse out of my driveway it is smooth.

My car dash thermometer stays pretty close to the bottom low then after about 4-5 minutes it shoots up to 190F and stays. Gas mileage is also very poor.

I looked up a tutorial which shows the parts needed and how to replace the sensor : [URL] .....

I removed the engine cover and believe I found the coolant temp sensor in the spot the tutorial shows. My question is if there is anything I should be aware of before attempting to replace this sensor that this tutorial doesn't cover? I took a screenshot of what I believe is the coolant temp sensor.

Golf IV / Jetta IV :: Coolant Temp Light Came Flashing On - Oil Getting Into Coolant

Okay so recently I was driving my 2000 Jetta and the coolant temp light came flashing on, when I went to check the coolant I was surprised to discover that it was like a mud brown color, almost looks like peanut butter. From everything I have read this can be from a few things, either rust build up that is gunking everything up and oil getting into the coolant somehow. I'm pretty sure its rust build up but I was wondering what everyone thinks about this, I was also not using G12 coolant which I'm told now is the premier brand for VW's.

Golf IV R32 :: Coolant Temp Sensor Code 16502?

Threw a coolant temp sensor code yesterday morning:

16502 - Engine Coolant Temp. Sensor (G62): Signal too high
p0118 - 002 - Lower Limit Exceeded - Intermittent - MIL ON

Does throwing that code once mean I need to replace the CTS immediately or am I safe to clear the code and see if it returns? No code today after a 40 minute drive.

Golf IV / Jetta IV :: Overheated - Coolant Temp Light Came On?

Today was the first time my wagon has stranded me due to a mechanical issue. During city driving my coolant temp light came on so I pulled over to check it out. The fans appeared to be working, the coolant was a fair bit above the normal mark, but I'm not sure the water pump was running. I couldn't feel anything when I squeezed the top radiator hose. This is an '03 with about 50k miles on it.

I'll be taking it in Monday morning so I was curious what people's thoughts were. If it's the water pump is there anything else I should consider getting replaced while I'm at it? I'm still on the original timing belt, a change I've been delaying a long time since I drive so little so it might be time to bite the bullet and do it.

Golf IV / Jetta IV :: Error Code P0113 - Intake Air Temp Sensor

My 2003 Mk 4 Golf have had a lot of error codes and I have cleared most (O2 sensors, thermostat, and Mass Air Sensor) I now have an error P0113 which is the Intake Air temp Sensor.

So I need to clean the sensor first then maybe replace it, but I can't find the sensor on the intake manifold.

I have looked all through the U-Tube info, but nothing matches my 2003 Golf 2.0L ...

Golf IV / Jetta IV :: 2001 - Code P0102 / Air Temp Sensor Circuit Was Low

2001 jetta 2.0 VW guys a while back I was pulling a code saying that the air temp sensor circuit was low I believe it was P0112 so I replaced the maf with a bwd maf. Said it was for the car. Was fine for a day but now it has a P0102 code and the epc stays on (rough idle) what could be wrong ? Is it because the car hasn't learned the new sensor yet because I've only drove 10km or do I have a faulty sensor. BTW replacing the maf fixed the P0112 code

Golf IV / Jetta IV :: CEL Is On For P0116 Engine Coolant Temp Circuit / Range Or Performance

My CEL is on for P0116 Engine Coolant temp circuit, range or performance problem. I replaced the CTS, thermostat, and did a complete coolant flush/replacement last November. Car worked well over the winter no issues. Last week when the CEL came on it gave me P0301 and P0440 as well. I did a reset and the lights stayed off for the week. Then P0116 came back. Is it possible that the CTS is bad again? I measured the resistance on the CTS and hot it is about 300 ohms and cold is 2.45k ohms.

Golf IV / Jetta IV :: 2001 - Misfire After Replacing Coolant Temperature Sensor

I drive a 2001 Jetta with the 2.8 v6 with ~125k miles

So for a while my car was giving me a false read on my temperature so I replaced the sensor. I actually followed instructions from a thread on this site. [URL] ....

Now when I go to drive my car, it runs sluggish and misfires if I really give it some gas. CEL is on(however does not return a code when hooked to a computer), and flashes when gassed hard.

I've checked to make sure spark plug wires were reconnected correctly and securely. No leaking has occurred from the temp sensor. shift rod drive unit is reconnected correctly.

Passat (B5) :: CEL Code P1296 - Coolant Temp Sensor?

I was driving today when the CEL came on, I scanned the car which gave me 1 code: P1296.

I googled it and said it is possibly the coolant temp sensor?

The Engine temp was normal at 190' or just below even after quite a bit of driving today.

Would the problem just be the sensor or should I be looking for other problems as well?

The car is a 2002 B5.5 AWM 1.8T Tiptronic.
