How is the coolant temperature sensor on a car controlled?
A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function. You can use a Digital multimeter. to check the Ohm between the pins.
How can I tell if my coolant temperature sensor is bad?
To diagnose the coolant temperature sensor, you need a repair manual for your car model to find what measurement values you should expect from the coolant temperature sensor. Connect an OBD2 Scanner and look for related trouble codes. Check the live data to see the temperature from the sensor.
How much does it cost to replace a coolant temperature sensor?
Unscrew the ECT sensor in an anticlockwise direction, similar to how a spark plug is removed. Install the new sensor and reconnect the connector cable. The average replacement cost of the Coolant Temperature Sensor is between $100 and $220. The labour cost is between $40 and $140 while the part itself costs between $50 and $80.
Where is the coolant temperature sensor on a Porsche Boxster?
This sensor is simply held in place by a rubber grommet that is attached to the intake manifold on the right side of the engine near the air pump. The coolant temperature sensor is located on the pulley side of the engine off to the left side of the car near the cylinder head.
What is the knock sensor on a Porsche Boxster?
Shown by the blue arrow is the oil level sensor / oil temperature sensor. This is a somewhat unique sensor in that it contains both level and temperature sensing functions within a single unit. Next to it is the knock sensor (purple arrow).
What should the temp of the coolant sensor be?
Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.
Why does my Porsche Boxster have an AOS problem?
The AOS has caused numerous issues on Porsche engines and is an item to be closely monitored. As the membrane in the AOS fails, oil is sucked into the air intake. Initially this can show up as a check engine light for fuel adaptations with oil being deposited on the o2 sensors causing emission faults.
