Since its introduction in 1983, the Toyota Camry has been a formidable competitor in the mid-size class of vehicles. When the Camrys third generation -- 1992 through 1996 -- came about, Toyota satisfied buyers' hunger for larger, more comfortable vehicles by increasing the size of the popular sedan and giving it a sleeker appearance. The 1994 Camry came standard with a 125-horsepower, 2.2-liter four-cylinder engine and had an optional 188-horsepower, 3.0-liter V-6 available. The coolant temperature sensor reads the temperature of the coolant as it exits the engine, so that the vehicles computer can determine when to engage the cooling fans. The sensor also controls the Camrys temperature gauge. Replacing the sensor is the same process on the 2.2- and 3.0-liter engines.
Instructions
Removal
- 1
Allow the Camry to set until the engine is cool to the touch, if needed.
2Trace the Camrys upper radiator hose toward the engine until you reach the metal tube connecting it to the engine -- this is the coolant outlet tube. Find the coolant temperature sensor screwed into the top of the coolant outlet tube.
3Pull up on the locking tab on the coolant temperature sensors wiring harness, and pull the harness from the sensor.
4Remove the coolant temperature sensor from the coolant outlet tube with a ratchet and deep-well socket.
Installation
- 5
Coat the threads of the new coolant temperature sensor with a conductive thread sealer. Allow the sealer to cure for the time specified by its instructions.
6Hand-tighten the coolant temperature sensor into the coolant outlet tube, then torque it from 12 to 18 foot-pounds with a torque wrench and deep-well socket.
7Plug the wiring harness into the sensors receptacle; listen for the locking tab to click into place.
