Mass Airflow Sensor 97 GS-R

[swingkid02]

My check engine light came on and the code read a problem with the mass airflow sensor. I looked on the air intake near the throttle for the sensor and couldn't find it. Does anyone know if it's hidden somewhere or if I'm just missing it? Thanks, Rob

WHAT??

Verify the ECM error code number. I don't believe your car is supposed to have an airflow sensor.

Maybe AutoZoned gave you the correct code # but the wrong description. Any code over P1000 isn't the same for different manufacturers.

Hondas don't have MAFs, they have MAPs. Your MAP sensor should be located on the throttle body.

The error code that we're getting isn't over 1000, it's P0100 which is Mass Airflow Circuit Malfunction... I just need to know where it is.

Thanks

It's a MAP (manifold absolute pressure) sensor malfunction and the sensor is on top of the TB.

Here you can find the MAP sensor diagnosis and location for a European Civic with B18C engine which is similar to the Integra GS-R: http://www.honda.co.uk/owner/CivicManual/pdf/11-40.pdf

BTW what did you use to scan the DTC? Because you should have got something like P0108 or P0107
