So I got a 98 GMC sierra and the ect sensor that is on it only had one wire running to it. Obviously the previous owner tried to make something work. I bought a new ect sensor and pigtail to rewire it but can't find the ground wire anywhere. Looking for a wiring diagram?
View 14 RepliesMy 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 ....
I drove my 99.5 7.3 F-350 1 mile to a friends and hooked it to the OBDII to get a code for my abs light.it had not been drove all day. we hooked into the pcm and he noticed the temp at 375* it was idling. is this right he didnt think it should have been that high???Will the engine coolant temp sensor, if it were bad,show a high temp of 375*? On the OBDII it showed a temp of 375* .....
View 14 RepliesI was going to order a ECT gauge and was wondering where to mount the sensor. I have already used the port under the T-stat for the coolant filter. The gauge sensor is a 1/8 NPT. Would the block drains be a good location, or is there another location that will work.
I know the coolant filter housing has a port, but I would prefer the sensor be on the motor.
2002 ford sport trac.I have been having an ongoing issue that started with the engine cranking but would not turn over until an hour passed. After replacing multiple parts (cam shaft sensor, crankshaft sensor, ignition pack) I am now down to poor fuel economy as the last of the issues (roughly 12 in the city and 15 highway). I was told the issue may be the engine coolant temperature sensor going bad so I decided to replace it. I found this was very difficult due to it being a plug and locking pin design and in a very tight spot in the engine.
I tried to purchase a replacement and the parts store kept trying to insist on selling me a part with threading. I finally found someone that figured out the issue and found the part for the 2001 sport trac had the same plug style with clip that did fit but was shaped a little different on the sensor end which I assume was due to being aftermarket. I noticed that there were two plugs side by side and the one easiest to access was on the left and I was told the one on the right was the sensor that gave the temperature reading to the gauge.
After installing the engine coolant temperature sensor I found the temperature gauge on the dash now will not respond and is sitting below the cold end of the gauge completely off. Is it possible this is because the part was for a 2001? Is the sensor on the left (passenger side) the engine coolant sensor?I would hate to put the old sensor back in just to test if that's the issue due how difficult it was to put that locking pin back on. What to check that could resolve the gauge issue before pulling this sensor back out?
I have a 2000 Celica GT and I suspect the coolant temp sensor has gone bad....the fans are not turning on and I'm not getting any hot air out of the heater.....where is the coolant temp sensor located on this thing?

View 1 RepliesI 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.
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?
View 3 RepliesThrew 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.
I need to replace my coolant temp sensor, but can seem for find where it goes. Bentley says it's on the rear coolant line, but that eludes me as well.
View 6 RepliesI have a B5.5 with the 2.8. I'm changing the coolant temperature sensor, but cannot get the thing out of the harness. With as tight as the working area is, I really don't want to screw-up the harness. How to get this out? I have the sensor out of the pipe the crosses between the heads and only need to remove it from the harness.
View 2 RepliesOk so I recently started noticing my car was overheating and the sensor would go off saying coolant temp hot. So I started by adding coolant that didn't work. I than replaced the thermostat didn't change. I saw the water pump was leaking and changed that but before I did I was driving it home one night and the engine stopped and I barely had control of the car. Now the water pump is new and I don't know what the problem is. I think it's the head gasket ???
View 6 RepliesMy CEL came on and the code said Coolant Temp Sensor High Voltage. Since there are 2 sensors, and my gauge isn't reading off, about 200F constantly, I assume the bad sensor is the water pump sensor. Also, is there a diagram of the sensorny locations and the easiest way to access them to swap them out. I have already purchased the sensor and gasket, just don't want to replace the wrong one or screw something else up in the process. It appears to be an easy job.

View 3 RepliesI just replaced my CTS, and I noticed that there is a small section of exposed harness wiring between the end of the loom and the CTS connector. I can't tell if it came loose when I swapped the sensor, or if it was this way for awhile, but all of the other harness connections around this area are completely covered and the loom end doesn't seem to clip into the connector or anything. If I were to try and seal it, I would need to use tape.
How hot does this area get? It seems like there shouldn't be exposed wiring here.

P3081. What the hell is this code. I think it is a coolant temp. sensor issue.

View 5 RepliesMy truck has been having idle surge, low engine power, says stable tracks is off, computer said TPS pedal sensor. I replaced it. Within 3-4 days my truck does the same thing. I turn it off and eventually my truck runs fine with the exception of my engine light is on truck runs good. I put the computer on it again while the truck running bad and it continues to say it is the TPS sensor.
View 2 RepliesI 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.

Okay getting ready to trade in my Truck. So I removed all the extra things I put on there while I was in college, the amp, fog-lights, and analog oil pressure sensor along with their wiring. It was pretty easy minus removing the oil pressure sending unit part.
I had to unplug the MAF to move the intake out of the way while I was repairing a loose vacuum tank. But I forgot to plug it back in when i closed everything up. I started the truck and drive it about a half mile before I was able to pull over and plug it back in. Truck ran and shifted fine after that, but the CEL came on. P0119 Coolant Temp Signal Intermittent. Guy at Autozone said it was Intake Air Temp Sensor intermittent and I could just replace the part, but they were showing a separate part even though it is built into our MAFs.
So now the CEL is on, can get it to go away. Truck is a little jerky every once in a while, like a misfire, when between 50 and 60. Before all this the CEL was off. Now after I cleaned it up and removed some of the superfluous accessories, I get a CEL. I wanted to trade it in this coming weekend without having to take a loss because of the CEL or spend more money to fix it.
