mohamedeladawy@hotmail.com Posted March 25, 2007 Report Share Posted March 25, 2007 P0100: The PCM determinded that a malfunction exists in the electrical circuit for the mass air flow or volume air flow sensor. This code points towards a possible wiring problem, i.e: short to ground, short to power, or an open circuit. P0150: The PCM has determined that a malfunction exists in the electrical circuit for oxygen sensor 1 in bank 2. soooooo... wat does this mean and how do i repair it? (keep in mind that i had idle speed sensor, abv vent solenoid, and shift be solenoid trouble codes.) Quote Link to comment Share on other sites More sharing options...
mohamedeladawy@hotmail.com Posted March 25, 2007 Author Report Share Posted March 25, 2007 just to add to wat i have to do: i need to replace all strut bumpers, spring insulators, and possibly a strut mount or two (along with the struts themselves), right upper leading link (i diagnosed that one myself), two motor mounts (front and rear), and the above sensors. milly is runnin deep in my pocket. o and that damn waterpump.

///BHRpowered Posted March 25, 2007 Report Share Posted March 25, 2007 0100 - MAF circuit, I would take it out, inspect, clean, check connections. 0150 - O2 sensor malfunction, bank 2 sensor 1, might just be time to replace. Quote Link to comment Share on other sites More sharing options...
Super S 69 Posted March 26, 2007 Report Share Posted March 26, 2007 0100 - MAF circuit, I would take it out, inspect, clean, check connections. 0150 - O2 sensor malfunction, bank 2 sensor 1, might just be time to replace. Yeah like he said change your O2 sensors asap. Or else it will kill the cat or precats. Quote Link to comment Share on other sites More sharing options...

latinopikachu Posted March 26, 2007 Report Share Posted March 26, 2007 perhaps it is a cause of your air filter Quote Link to comment Share on other sites More sharing options...

mohamedeladawy@hotmail.com Posted March 26, 2007 Author Report Share Posted March 26, 2007 and oh fruity genius, how would it be? my air filter is clean and all the sensors have been put back in place (well there is only one and the maf). i checked the connections and that plastic dangling thing and everything seems fine. im now confused Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted March 26, 2007 Report Share Posted March 26, 2007 The only time I have bought them tis been from ngk, which I got from www.sparkplugs.com or something, they carry o2 sensors also Quote Link to comment Share on other sites More sharing options...
mohamedeladawy@hotmail.com Posted March 27, 2007 Author Report Share Posted March 27, 2007 but wat of the maf? and wat is the vaf? or is that just another name for the maf? Quote Link to comment Share on other sites More sharing options...
mts Posted March 27, 2007 Report Share Posted March 27, 2007 Maybe your MAF is dying? near 300K miles.... Quote Link to comment Share on other sites More sharing options...

mts Posted March 27, 2007 Report Share Posted March 27, 2007 He is right Camel, maybe you are not getting the sealing... OR your AIR FLOW HAS CHANGED, AND THEREFORE OUT OF SPEC Quote Link to comment Share on other sites More sharing options...

Renboy Posted March 27, 2007 Report Share Posted March 27, 2007 MAF - mass air flow sensor VAF - volume air flow sensor They're basically the same sensor, just different measurements. The milly uses a MAF, not a VAF. If you have a manual, or someone has one near them they can check the procedure to test it. But, Lat may have been half-correct. It's not the seal around the filter that makes any difference, it's any post-maf seal that does. You could be pulling unmetered air into the system, and thus tripping a code. Check any seal between the maf and throttle body. If those are correct, then it could the maf that's the problem. Or the temp sensor that you chose to leave hanging. If the mass is saying one thing, the temp saying something, and the o2 sensors reading something way off, then somewhere down the line there's a problem. The intake may actually be pulling in colder air than what's in the engine bay (what the temp sensor is reading) and thus causing you to run lean.

mohamedeladawy@hotmail.com Posted March 27, 2007 Author Report Share Posted March 27, 2007 o wait...soo if there is a sensor after the maf but it was located b4 the maf...that would throw a code? Quote Link to comment Share on other sites More sharing options...
Renboy Posted March 27, 2007 Report Share Posted March 27, 2007 Which sensor? Quote Link to comment Share on other sites More sharing options...
mohamedeladawy@hotmail.com Posted March 27, 2007 Author Report Share Posted March 27, 2007 that lil dangling sensor. i knew that it was originally located b4 the maf but there wasnt space so i put it after the maf. would that throw the code?
