I have a 00 civic si with a h22a1 swap. My MAP Sensor went bad and I changed it out and it still runs the same. A guy with an accord said he had the same thing happen to him and it was the relay for the map sensor. Does anyone know where that relay is or if I even have since I don't drive an accord?

never heard of a map sensor relay and neither has the honda service express web site.

Why would there be a relay for the MAP sensor? It does nor need a switching curcuit.

Don't know, but my engine runs incredibly rich. Like to where it bogs down and it even has unspent fuel shooting out the exhaust. Last time it was a map sensor. This time....

there is no relay for the map sensor. All three wires to the sensor run directly to the ECU.

which ECU are you running on the swap?
