Hello!
Didn't find any theme for this: is somebody changed MAP sensor for 2002 GV (3.3 V6 128kW), what possible causes may be, if i use MAP sensor with code 56041018AC (original in car is the same, but **AB end).
I didnt find any difference for them, only **AB use 'Jtec' module, but **AC use 'next generation module', also sensors are little different by look: one have plastik 'ear' in left side, second have right side.

Wanna change cause OBDII gives trouble codes
- P0106 Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem
- P0172 System too Rich (Bank 1)
- P1299 Vacuum Leak Found (IAC Fully Seated)

.. and car dont wanna work normal way..

 

It's the type of engine controller used, next gen has 4 connectors on the PCM and the other has 2. Use the one made for your controller.

Are you sure you don't have a vacuum leak?

 

I and the service guys searched all hoses, but nothing found and hear. Yesterday i change MAP-sensor to this **AC version, car start correctly and working fine
I drived more then 100 km, and all was OK. Hopefully this will work about 1 week, when i get new MAP-sensor, with **AB end (which is original for my car).
Elektrik from service test impedance of both sensors, and that is different, so its good to put right sensor, who knows what can happened in time.

 

Only leak which maybe was, was from the sensor himself, cause sensor dont had some plastik cover from top, which is clued i think there..
**AB had 3 wire connector, and also **AC sensor have 3 connector..
