Need to know what engine you have.
The ECU is in the engine compartment on a 2002 Pontiac Grand Am. It is the sensor behind the converter.
The intake air temperature sensor is located on top of the intake. In a 1990 Toyota Camry the air temp sensor assures the ECU the engine is running at optimal temperature.
what year? Are you talking about the ecu? I am looking for the coolant temperature sensor on a 2001 ford mustang 3.8.
There is not a single ECU sensor. There are dozens of sensors on this car that feed the ECU
The IAT sensor, or intake air temperature sensor, is located on the tubing the of intake on a 1991 Acura Integra. This sensor reports the temperature of air coming into the engine directly to the ECU.
It's not a part, there are parts... First of ECU, then EGR valve, idle control valve, MAP sensor, oxygen sensor.
You can start with the 02 sensor. if that does not fix the problem then you may have to consider the ECU.
If it's cold outside, it's because ECU use ambient temperature sensor and coolant sensor to manage RPMs. After you start the car the coolant temperature is low and ECU sets RPMs very high, when it gets warm RPMs drop down until engine reaches operating temperature.
Follow the upper radiator hose to the thermostat housing. The coolant temperature sensor for the ECU (2-pin connector) is on the driver's side. The temperature sender for the guage (1-pin connector. is on the opposite side.
The 2002 Ford Windstar ECU can be found on the firewall in the engine compartment. The ECU will be on the drivers side of the firewall.
The coolant temperature sensor that controls ECU cold start fuel enrichment and ignition timing is located behind the power steering pump on the bottom of the intake manifold right behind the thermostat housing.
It has no governor. Speed is controlled by the ECU.
