Beck/Arnley Temperature Sensor

Part No. 158-0421 Warranty Details  

See if this part fits a specific vehicle.

Check Vehicle Fit

Used to sense the temperature of the engine at the computer to adjust the fuel mixture. When the computer senses that the engine is cold through the use of the sensor it will increase the on-time of the injector. This enriches the fuel mixture the same way as using the choke. It also uses the sensor to determine when to turn the engine cooling fans on and off. Helps restore the original engine temperature, proper engine idle and proper air fuel mixture.

    Comments about Beck/Arnley Temperature Sensor:

    I didn't read the temperature properly when the coolant was cold and therefore the computer didn't out put enough fuel to immediately start the engine, this caused start up hesitation, upon warm up of coolant, it functioned as it should have.

    This issue was resolved using a used OEM coolant temperature sensor from the junkyard...

              When trouble shooting engine stalling / hesitating this should be one of the first parts to replace. Look here before replacing something more expensive like the distributor assembly.

                  A:

                  With reference to your inquiry on the Beck/Arnley Temperature Sensor - part# 158-0421, the coolant temperature sensor may be the possible cause of the problem. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem. For any further assistance, please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.

              • Q:

                On a 1990 Toyota Camry 3SFE 2.0 liter model, there are 2 sensors on the water outlet. Do you know if there are two different ones or are they the same temp sensor doing two different things: I assume one sensor controls the fan and from the description of this product it controls the fuel/air mix.

                hope to hear soon, thank you

                  A:

                  One should send information to the computer on the temperature of the coolant and I believe the other is the sensor which tells the computer when to turn on the cooling fan.

                  This is the EFI coolant sensor. Viewed from the front of the engine, it is about 1 inch to the left of the main temperature sensor that has a green body. Both of these sensors are side by side on the driver side of the engine.
