Chevrolet K1500 MAP Sensor

Chevrolet K1500's MAP Sensor is a significant component that sends information regarding positive air pressure to the intake manifold to the ECU for fuel adjustment. In fuel injected engines, the MAP Sensor calculates air density and plays an important part in the speed density method of determining the quantity of air to fuel to mix for the combustible one. In naturally aspirated engines either a MAP or a MAF sensor can be used but in forced induction engines both are used. The MAP Sensor also helps in on board diagnostic and helps in testing the efficacies of the EGR valve; it is important when it comes to the metering of the fuel and performance of the engine.

Each OEM Chevrolet K1500 MAP 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 K1500 MAP Sensor Parts Questions & Experts Answers

  • Q: What is the purpose of the Manifold Absolute Pressure (MAP) sensor for Chevrolet C1500 and K1500?
    A: The Manifold Absolute Pressure (MAP) sensor monitors the intake manifold pressure changes resulting from changes in engine load and speed and converts the information into a voltage output. The ECM/PCM receives information as a varying voltage signal from closed throttle (high vacuum) to wide open throttle (low vacuum). The ECM/PCM uses the MAP sensor to control fuel delivery and ignition timing. Performing the following test will set a diagnostic trouble code and illuminate the Service Engine Soon light. Clear the diagnostic trouble code after performing the tests and making the necessary repairs. The MAP sensor is located on the upper intake manifold plenum. Check the terminals in the connector and the wires leading to the sensor for looseness and breaks. Repair as required. Before checking the MAP sensor, check the voltage supply and ground circuits from the ECM/PCM. Disconnect the electrical connector from the MAP sensor and connect the positive lead of a voltmeter to the gray wire terminal (and the negative lead to the orange/black or black wire terminal at the harness connector. Turn the ignition key On-the voltage should read approximately 5.0 volts. If the voltage is incorrect, check the wiring from the MAP sensor to the ECM/PCM. If the circuits are good, have the ECM/PCM checked at a dealer service department or other properly equipped repair facility. To check the MAP sensor operation, reconnect the connector to the MAP sensor and using a suitable probe, back probe the light green wire terminal of the MAP sensor connector. Connect the positive lead of a voltmeter to the probe and the negative lead to a good engine ground point. Turn the ignition key On-with the engine not running the voltage should read 4.0 to 5.0 volts. Start the engine and allow it to idle. The voltage should decrease to approximately 0.5 to 2.0 volts. If the test results are incorrect, replace the MAP sensor. Access the MAP sensor. On TBI systems, remove the air cleaner assembly. On Central SFI systems, remove the intake air duct and resonator from the throttle body. On MPFI systems, remove the upper intake manifold from the engine. Disconnect the electrical connector from the MAP sensor. Remove the retaining bolts and draw the MAP sensor. Replace the MAP sensor seal in the upper intake manifold, if equipped. Installation is the reverse of removal.
