Is the O2 sensor required for smog testing?
The O2 sensor is an emissions control device, and is required in states that use smog testing for annual vehicle inspections. States like California are especially strict with smog testing, so its important to make sure that your vehicle’s O2 sensors are functioning properly.
How can I check the temperature of my engine?
The system should be checked with an infrared temperature probe to see if the temperature of the engine is close to that the computer is seeing from the coolant sensor. If the coolant temperature sensor input to the computer is within about ten degrees of what the infrared tested is reading on the outside of the sensor then this would be okay.
What are the temp sensors on a 22RE?
As I understand it, the 22re in my generation effectively has 4 temperature related sensors (assuming an SR5 22re): A main Temp Sensor for the ECU, a Temp Timer Sensor for the Cold Start Injector, a Temp Switch for detecting overheating in 4WD, and a Temp Sender for the dash gauge.
Who are the temp senders on my car engine?
I think I have tracked the issue down to possible Temp Senders on the engine by the PO.
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.
What’s the name of the coolant temperature sensor?
Coolant temperature sensors are also known as engine coolant temperature sensors or ECT sensors. The principle working of this sensor involves the use of an electrical resistance which measures the temperature of the coolant.
