Why p0068 code - 2005 Buick LaCrosse

Hi. Thanks for your question. For assiatnce n repairing codes on p0036,p0108 and p0068 you can visit https://www.reliable-store.com and download the entire workshop manual which includes all the information along with the diagrams for better understanding. Good day!

Here's a link to the P0068 code. P0068 MAP MAF Throttle Position Correlation Here's the link to the P0175 CODE. P0175 OBD II Trouble Code

Hi. Please concentrate on fixing p0068. this is to do with airflow and fuel/ mixture. maybe air mass meter. these can cause faults p0420 and 0430 to come on. after p0068 is repaired clear all faults and take the car on a long drive to clean out the cats, reassess if the cats are actually faulty at a later date.

Code P0123-THROTTLE POSITION SENSOR 1 CIRCUIT HIGH and code P0068-MANIFOLD PRESSURE/THROTTLE POSITION CORRELATION. Without having the vehicle to properly test, and based on the information I have it sounds like your throttle position sensor has kicked the bucket. Replacing the sensor with a new one should solve your problem.

codes p0068 refer to Manifold pressure sensor/mass air flow sensor--throttle position correlation--causes ---wiring---map sensor---maf sensor--mechanical fault.
code p0108 refers to manifold absolute pressure(map) sensor/barometric pressure (BARO) sensor--high input. causes ---wiring short to positive---map sensor---baro sensor---ecm.

both codes are for maf sensor is it plugged in

The generic code is for a problem with the sensor reading for the mass air flow and the throttle position sensor. The computer is not liking the two readings because they don't match up.
Could be a sensor problem or a vac leak among other things.

MAP (Manifold Absolute Pressure) Sensor or MAF (Mass Air Flow) Sensor or TPS (Throttle Position) Sensor. Not that hard you just need to know where to look so I will give you a link to look up codes :-)

Hi
code P0068 = MAF/MAP sensorthrottle position correlation
code P0108 = MAP/BARO circuit high input
code P0441 = EVAP emission control system purge flow fault
take it infor a service
cheers Rob.

p0068 is Throttle Position sensor inconsistent with Mass Air Flow sensor.

couldn't find the other 2.
