The input turbine speed sensor is located just behind the bell housing area of the case. I believe the trans controller is the only module that needs that info. The Crank Position Sensor give engine RPM info and it is located on the bell housing near the engine block. I hope this helps. Mar 29, 2009 • 1999 Dodge Intrepid.

Aug 4, 2022 #1 Here is a more detailed list of the most common reasons why a temperature gauge stays on cold. 1. Faulty Engine Coolant Temperature Sensor. As we talked about, the most common problem with a faulty engine temperature reading is the coolant temperature sensor itself sending wrong information to the cluster. Hi kegless. I have had a quick look at my CD based service information, but it is unhelpfully not specific about the control signals. However, the Heater plug control unit M015 appears to be a glorified high-current relay, and normal practice for Fiat with similar setups seems to be to supply the coil with +12 volts and to earth the other end when needed by means (presumably) of a Flame Start device:-. This is the more unusual part of the system. This engine does not have glow plugs like most diesel engines (electrical heaters in the cylinders that help ignite the fuel when the engine is cold), instead it has a ‘flame start’ device in the inlet manifold. This is a single heater plug and an additional diesel supply MAP sensor, Fiat part number 050424527, cost £43.07, inside the box the part is Bosch part number 0 281 002 845 price £31.99 on ebay inc postage. If you look at the photo there is an inset of mine as extracted, totally clogged with an oil / carbon sludge. Mechanic suggested a faulty earth, off to Luton and return with not so much as a sniff of a repeat performance. Fast forward to this afternoon, 1500 miles later, on the A88 towards Le Mans. 20 miles into our journey temp guage goes to the top red light on again. Pull over at peage squeeze pipes, water flowing ok. Good morning. I was just wondering if anyone else has had a problem with the ext temp displayed on the dash. Mine is wildly optimistic. I was wanting to replace the temp sender unit but it seems as though I have to buy the whole mirror. Has anyone found an alternative way. Buying the temp 3. Points. 3. Aug 14, 2020. #1. After a bit of advice please, I have a 2005 Ducato based campervan and the coolant level light is on and the coolant bottle is at its correct level. The temperature when travelling is fine so I’m guessing it’s a sensor fault. My question is, where is it located and is it a job that can be done by myself? The average boost pressure sensor replacement cost is between $175 and $200. However, this cost can vary depending on the vehicle you drive and where you take it for repairs. If you’re looking to replace this sensor yourself to save a little money, you can, but most of the cost is in parts, not labor. The average boost pressure sensor costs qGjCG.
