The TMS Water Temp Sensor Wiring Adaptor is needed when you are upgrading to OBD-I (1992-1995 components) on a 3.2 or 2.8 liter engine. These earlier engines use two separate water temp sensors in the head, one for the ECU and one for the instrument cluster. Most of the 3.2 and some of the 2.8 liter engines do not have two holes drilled in the head for the early water temp sensors. This is due to the fact that the 3.2 and 2.8 engines used a combined water temp sensor. So we designed a easy to use plug and play wiring harness. The benefits are: No cutting and splicing, no trying to fine plugs and pins. We also suggest using TMS "3.2 in a 3.0" Coolant Hose Adapter P/N: TEN9931007 to make your life easier.

The camshaft position sensor is essential for assisting the engine DME by monitoring the camshaft's position. The data from this sensor is key to optimizing ignition timing and ensuring smooth engine performance. Often referred to as the CMP sensor, this component is crucial for the overall functionality of the powertrain. A failing camshaft position sensor can cause a range of issues, including engine stumbling, hesitation during acceleration, power loss, and even starting difficulties or complete failure to start.

This is the coolant temperature sensor used in many BMW models from the late-1990s to the mid-2010s. The engine computer relies on the coolant temp to set the fuel mapping for the engine. As the car warms up the computer changes the fuel mixture. If your car is running a bit rich (too much fuel) it could be because this sensor is failing and not sending the correct info to the computer. This sensor is located in a variety of places depending on the engine. But it's one of those easy replacement items 'while you're in there' when doing a water pump or thermostat replacement. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.
