I have a wire that is disconnected on the passenger side that is going to bug the crap out of me, I will take a picture and post it to see if I can verify what it is, and where it should go. Check spark, fuel injector pulse and fuel pressure, volume, quality and engine compression. When at operating temp after driving to work, if i turn it off and then try to restart, it will start right up. I will have to take a look at the drivers side. I started to unravel the taped wires and they must have been yanked off when the prior owner hit something!!! May 24, 2018 Followup from the Pelican Staff: There may be a seal available. Oh also added a leak stop chemical and prior to heat worked. On idle warm up there is no significant temp in upper or lower hose based on touch.
Please help me find it. Before replacing it, pressure test the cooling system to be sure it is properly sealed. How can this issue be isolated to relay or fan? I see no other wire in the driver side wheel well, the only wire s that I have seen that were not hooked up were on the passenger side??? Third step will be to remove the probe and put a short wire jumper over the terminals in the probe connector. My best guess is the temp sensor. What are high and lo pressures when the compressor is on? I would always recommend soldering wires but if you are inclined enough to try the repair yourself, insulated crimp connectors should be fine for this circuit.
If it reads open circuit, the wiring is faulty. Inside the sensor body are two tiny metal contacts. The first sign you may have a problem with your external temperature sensor is if you have a really low reading. Thanks guys Hey guys, Philip, is this the sensor in question? Any clues on where else to look? Thank s November 27, 2017 Followup from the Pelican Staff: around 200-215°f - Nick at Pelican Parts Jr Comments: I have a 2002 bmw 330i having problems with the aux fan not turning on at all not even when I turn my a. Getting a Code P0116, replaced the coolant temp sensor and still pegs upon turning on and still getting a Code P0116. Now to find the wiring and where the wiring leads before:dunno: the sensor location. Temp outside says -40, then +122.
Do you have questions or want to add to the article? If it says -40 then it's effectively an open circuit. Now its completly packed up and stuck on -40. Can there be any way that these could be for the outside air temp sensor??? Usually they are not available separately. Do you think that changing the temperature sensor can solve the issue or it can be something else? I also have a inactive wire hanging from the passenger side that i thought was the temp sensor. Once you figure out what is missing, it will be easier to diagnose.
But recently I got the -40F or -37F temps again! The sensor is mounted under the car in the front wheel splash pan area. If the system is not working properly, a fault code will be set. There are three different body styles to choose from, including the convertible, coupe, touring, and saloon. June 21, 2018 Followup from the Pelican Staff: Check if hot coolant is entering the heater core. Here are some pix:Nice pics! He did check for and found no leaks. June 6, 2017 Followup from the Pelican Staff: Unlikely the under-spray would cause an issue.
I replaced my sensor some time ago and still reads +122 on the dash. Wrap it up clean and tight with electrical tape. This is caused by the sensor either being damaged, missing or having an open circuit; the wires leading to the sensor may have torn off in an impact. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Should this be related to bad thermostat? September 27, 2016 Followup from the Pelican Staff: One of the items you state is good has to b e faulty.
No lights lit on dash Check engine etc Spark plugs, air filter, petrol filter, crank sensor, petrol pump and all coils were replaced recently Im all out of ideas. You can buy the temp sensor yourself and try to plug it in, they aren't terribly expensive. I'm not sure what to do now? Any help would be greatly appreciated. The old sensor was written and not working based on the resistance in assuming. Replaced Temperature Sensor, Fan will not stop running until it drains battery. Here are some pix: How many wires are not connected to anything? Could it come from the bumper area near the center of the car, or does it come down with the fog lights and the horn wires? At room temp 75° room temp is has about 4.
I recently bought a transmission fluid temperature sensor from you guys and trying to do a diy and i cannot locate it. Install the new sensor into the lower radiator hose. If I disconnect the radiator outlet temperature sensor electrical connector, the fan will turn on, but doesn't work properly June 28, 2016 Followup from the Pelican Staff: I bet you have air trapped in the cooling system. Where is the sensor located on the car so that I can test it or replace it. January 5, 2016 Followup from the Pelican Staff: If you have hot hoses going into the heater core, and cold coming out, there is likely a restriction. Once you figure out what is missing, it will be easier to diagnose. If it's in your budget, replace the lower radiator hose also as preventative maintenance.
They can figure out what part or repair kit you need. Talking of a Bmw 318i E46 engine. March 13, 2016 Followup from the Pelican Staff: Thanks for the input on this one. But recently I got the -40F or -37F temps again! We're talking in the millions in Europe. Is my heater core plugged? It monitors the coolant temperature as it leaves the radiator.
