Chevrolet C1500 Intake Manifold Temperature Sensor
This sensor is known as the Intake Manifold Temperature Sensor especially in the Chevrolet C1500's and its function is to measure the temperature of the air that is going into the motor. This information is then sent to the Powertrain Control Module (PCM) and the fuel injector timing is modified in order to keep the air/ fuel mixture optimum during a wide range of operations. It is quite possible that different C1500 models produced over the years may call for the use of different Intake Manifold Temperature Sensors with some design and calibration differences to suit modifications. These sensors are designed to operate at certain flow rates and at certain injector levels to give some flexibility when performance parts are installed. However, conditions where RA has been increased greatly may require a different sensor in order to maintain absolutely correct reading and fuel efficiency on the engine. In sum, the Intake Air Temperature Sensor is important for the air/fuel ratio and the output of the engine.
Each OEM Chevrolet C1500 Intake Manifold Temperature Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
Chevrolet C1500 Intake Manifold Temperature Sensor Parts Questions & Experts Answers
- Q: What is the purpose of the Intake Air Temperature (IAT) sensor for Chevrolet C1500 and K1500?A: The Intake Manifold Temperature (IMT) sensor is a thermistor, a resistor that changes its resistance value with temperature. The voltage signal from the sensor to the PCM will be directly affected by this change in the resistance values. Resistance values decrease as the sensor temperature increases. The resistance values, however, increase as the sensor temperature goes down. It should be noted that only 1996 through 2000 models are equipped with an IMT sensor. This test sets a diagnostic trouble code and illuminates the Service Engine Soon light. Clearing the diagnostic trouble code after performing tests is mandatory together with making necessary repairs. One can find the Intake Manifold Temperature (IMT) sensor installed either in the air intake duct near the air cleaner or in it. Check that there are no loose terminals in the connector and breakages on wires leading to the sensor first of all. Make repairs where necessary. Before checking intake manifold temperature sensor, check PCM voltage supply and ground circuits. Disconnect electrical connector from IMT Sensor and connect positive lead of voltmeter to tan wire terminal and negative lead to black wire terminal at harness connector. Turn ignition switch ON- voltage reading should be approximately 5.0 volts. If voltage is not correct; check wiring between sensor and PCM. If circuits are good, then have PCM checked at dealer service department or other properly equipped repair facility. Disconnect electrical connector from IMT sensor with ignition switch OFF. With an ohmmeter measure resistance between two Intake Manifold Temperature sensor terminals on sensor while completely cold (50 to 80-degrees F). Reconnect electrical connector to sensor start engine and warm up until operating temperature is reached (180 to 200-degrees F), disconnect connector again, measure resistance. Compare your measurements against resistance chart for this vehicle. Should there be incorrect results of this test, replace intake manifold temperature sensor. A more accurate check may be performed by removing air intake duct and heating the sensor, with a heat gun or hair dryer while you monitor the resistance of the sensor. Disconnect electrical connector from sensor. Carefully remove sensor from air intake duct or air cleaner assembly. Installation is reverse of removal.
