MAP or Manifold Air Pressure Sensor

The MAP sensor is a main input to the ECM or engine computer. The MAP sensor measures the difference in air pressure between the intake manifold and atmospheric pressure. The ECM infers engine load from the MAP sensor reading. Learn how it works, what's the reference voltage and how to test it. unique information found only here.

Does a bad MAP sensor cause bogging/jerking during acceleration on a manual tranmission car? I have a 98 accord lx 5 speed and it is bogging/jerking. My CEL(Check engine light) is on for high/low voltage for MAP sensor.

Please reply as soon as possible, thanks :)

@JFIdelH Disconnect the MAP and run the vehicle that way. With MAP disconnected slowly goose throttle. You'd have poor performance, but it'll determine if MAP's the issue.

Another test is to disconnect EGR valve vacuum hose. If the EGR valve test solves your problem post back for the solution. Keep posting....

@ADPTraining Is the EGR valve vacuum the one next to the fuel rail/under the wires?

@JFIdelH Do a Google on it.... It's connected to a round valve...

1996 accord manifold MAP PID flatline 29"hg with engine idling CL ,should their be a decrease in inches hg with the engine running or is that normal for some cars?engine stalls when map disconnected .

I sorry my volt meter doesnt read Hertz .. just amps and volts current types

[JFIdelH]

@ADPTraining So are you telling to to disconnect the electrical clip for the EGR?

@bikr1975 No problem, you're not bugging me. Keep posting until you've solved your issue. I meant, post a video response, if you can do it. I need to see the sensor and others can benefit from our discussion... Good luck...

@ADPTraining do you mean a hho cell or the sensor?? sorry to keep bugging you like this.
