Hi, my name is XXXXX XXXXX I can assist you with this.
My first question to the diagnostic tec. that is saying that the maf and the temp sensor are "plausible" would be to have him compare the data that the maf/temp sensor is producing and compare that to a known good maf/ temp sensor and see if there is a substantial difference. This process can be accomplished with and scan tool that can read engine data for the mini... If there is a substantial difference in the (gps) gallons per second reading replace it. if not then press on to the next possible cause... Ido not blame you for not wanting to keep throwing parts at it.. fix it right the first time!!!
Thanks and God bless.
Hi, sorry you can not use a multimeter to test these sensors, you have to use a data specific scan tool to check this stuff, that is where the get you to pay for the diagnostics. its not about the resistance its about the signal that they produce that is interpreted by the engines computer that determines what fuel ratios that need to be established due to engine temps. Your best bet is to use a scan tool.
No problem, hope it goes well for you.
Just checking in, did you get it solved??
Try disconnecting the negative battery cable then step on the brake pedal for about ten seconds, reattach the cable. If you do not have any thing else wrong that should clear the processors memory and clear the check engine light for you.
Did that solve the problem for you?
