How to properly remove and install Coolant Temperature Sensor and Oxygen Sensor on Mazda Protege?

Question

Accepted Answer

Most parts are covered by a federally mandated extended warranty & details can be obtained from your dealer. A thermistor is the coolant temperature relay that vary its voltage output with temperature. In other words, as temperature falls, resistance rise and vice versa. Usually, a failure in this sensor circuit will set a Code 09. This indicates the need for connector or wire repair or sensor replacement. To test the sensor, you need to unplug the electrical connector and measure resistance across the terminals. It should measure 2,000 to 3,000 ohms when cold and 200 to 400 ohms when warm. Assuming the resistance values are correct, check for a reference voltage of approximately five volts with ignition ON. To substitute the sensor, undo it carefully and tape the threads with Teflon tape, then follow the reverse installation steps. A single or dual-stage oxygen sensor measures exhaust gases and produces a voltage. The PCM uses this signal to fine-tune the air/fuel mixture. Proper performance relies on the integrity of electrical connections, adequate supply of air, operating temperatures and unleaded fuel. To monitor the millivolt signal for the oxygen sensor, check if it changes with the engine speed. The heater circuit resistance and supplemental voltage can all be tested. To replace the faulty oxygen sensor, it requires the disconnection of the battery, lifting of the vehicle and removal of the sensor. Further, install new oxygen sensor by applying anti-seize compound to threads. Depending on the model year, either a vane-type potentiometer or a hot wire sensing element is responsible for the airflow sensor, which measures the airflow. Meanwhile, the throttle position sensor alters the fuel delivery based on the throttle angle. The intake air temperature sensor located within the air flow sensor changes its resistance according to the temperature of the air it 'sees'. This resistance is sent to the PCM to aid in its calculations of fuel injection strategies. The crankshaft position sensor informs the PCM of the crankshaft position for models from 1995 onward. Its resistance must be 500 to 600 ohms. The camshaft position sensor models on 1999 onward replace the distributor. Their resistance should measure between 0.95 to 1.25 K-ohms. In general, replacement procedures for these sensors first disconnect electrical connectors, remove mounting bolts, and install it properly.
