Fault Code Help

[LexusIS200Sam]

Driving slow up hill and the car miss-fired big time then the TRC OFF light was flashing on and off,

Ive plugged my IS200 into my new fault code machine, its come back with the code P0105.... i think this is to do with the map sensor? just want to make sure before i replace it.

thanks all

This is what i've got:

P0105 Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction

Possible causes: Wiring, Manifold Absolute Pressure (MAP) sensor, BARO sensor, ECM

stav where did you find that, mine says vaccume sensor failure lol... phoned up the local parts depo to get a map sensor and was told theres noting along the lines of a map sensor in there books for the IS200...

cars running very hesitant atm, defentlty nowhere near as quick as it used to be so want to get it sorted asap.

Its the same thing mate, 0bar Absolute is a vacuum.

Hmm basically the sensor that measures the inlet vacuum/boost is knackered (i think)

I have same problem going on...

I have tested the sensor and check'd wires, it shows almost correct data, but when i have drived about a week the car goes to "safe-mode" and warning lights light up.

Could it be cause of our cars are charged, and ecu doesnt like that cause its not programmed to get positive pressure ?

i wonder if there are any uprated vaccume sensors that would fit, My mates cosworth knocks his vac sensor when he has the boost turned up.. hes now put a 3 bar sensor and had no problems.. may be worth looking into it, im going to replace it with the standard part but if it happens again look for a uprated one.

[sparkystav]

Possibly, maybe the supra standard part will fit? cause obviously the IS200 part isnt ever ment to go into boost normally.

replaced the vac sensor and turned the light off with my OBDII reader, no problems as of yet :)
