How to Check and Replace the MAP Sensor on an Acura Integra?

Repair any breaks in the terminals and wires connected to the sensor's electrical connector if it doesn't fit snugly at the sensor and check for a good fit with the electrical connector. See which MAP sensor wires from different model colors. On Civic and CRV models the wire colors for power are yellow/red, for ground green/white, and signal to the PCM red/green. Yellow/Red supplies power to Integra models of 1994 and 1995 with 81881 engine, Yellow/White for 818C1 engine, White/Yellow is the signal to the PCM, Green/White is the ground. For 1996 and later Integra models, Power is yellow/red, signal the PCM red/green, ground green/white. Remove the MAP sensor connector from the harness and turn the ignition key on with the engine off, then 5 volts should be present between the harness side of the connector and the power wire; repair breaks and connections in the harness side if necessary. Detach from the throttle body away from the sensor, keeping the electrical connector attached by removing the mounting screws. After removing the sensor base from the throttle body, make a connection voltmeter betweet ae signal wire and body ground; the voltage should decrease as the vacuum increases. If readings are incorrect re preferably the MAP sensor. To remove, first disconnect the electrical connector from the MAP sensor, remove the sensor from the throttle body using screws, then install the new sensor in reverse of removal steps.

Acura Integra MAP Sensor

The MAP Sensor of the Acura Integra measures absolute pressure inside the intake manifold and sends this information to the ECU for correct air fuel delivery. This small plastic device detects the presence of positive air pressure to enable the ECU to calculate the density of the air, which is applied to set the injector pulse width and change the ignition timing. The MAP Sensor supports the speed density method for naturally aspirated engines when it provides data continuously. It works with a signal from the intake air temperature to estimate air mass. Unlike vacuum, the MAP Sensor reads absolute pressure, and the output assists on-board diagnostics in verifying the function of exhaust gas recirculation. The MAP Sensor gives reliable pressure feedback, allowing every Acura Integra to idle smoothly, respond well to the throttle, and use fuel efficiently without a separate mass airflow meter. The unit is lightweight but, at the same time, a critical component of the Acura intake system that delivers reliable Integra performance. It is compact, plastic, and connects directly to the manifold. The engine management system of the Acura Integra continually samples manifold data from the MAP Sensor so that fuel trims remain balanced under different driving conditions.

We provide a broad range of OEM Acura Integra MAP Sensor at unbeatable prices on our website. For your OEM parts, You can count on the guaranteed quality, manufacturer's warranty, outstanding customer service, and prompt delivery. We look forward to your visit.
