problem with MAP sensor reading
hello... i am a noob here so pls excuse any stupid questions that i may ask.
i have a B16A motor in my JDM EK Civic SiR. i have an Apexi Neo installed and i can see the MAP sensor readout there. the problem is, the PRS is never coming to 0. it comes to -6 or -5 but not to 0. i have replaced the MAP sensor but still the same thing. as a result, the car is slower and feels sluggish. but when the readout came to 0, it literally flew. even with the ignition on only (with motor off), the readout is -6 kpa. i have rechecked the apexi neo wiring and all the settings are 100% accurate. please help me to resolve this problem |
Is the CEL ON?
Do electrical troubleshooting of the wires between the MAP sensor and ECU. It's also possible that the ECU is bad. |
no..the CEL is not on. i double checked the wiring of the MAP sensor to the Apexi Neo to the ECU...no faults.
it may be a silly question, but if wiring prob was there, wont the CEL be on as it would detect certain readings from the MAP?? it was working fine for over a year and i didnt mess with the wiring at all |
Not all circuit faults will throw a CEL code. Did you test MAP sensor wires for both continuity/resistance and voltage. Isn't it also possible that the Apexi Neo is faulty?
