CODEP0101, M1C AND M2C TEMP

Hi guys

Just drove back from Houston to San diego, the trip is ok but worry so much the I got the Cold, I got engine light when I drove to Houston, P0101 which is MAF or VAF, I change the air filter just hope it help until I got back to San diego however did not help I had to clear out the code about 3 times, on the way back about 400 miles the engine light came back and I saw the M1C and M2C temp, the highest for M1C was 240 degree and M2C was 213 degree, I am so worry but continue to drive home, I did clear out the code 2 times on the way back, every time I clear out the code M1C temp did drop alot and stay about 203 also M2C, I noticed that M1C and M2C temp is NOT dynamic update when temp is up and stay up until you turn the car off and turn the car back on to read temp again.

I had a couple question guys so please help me out.

1. Should M1C and M2C temp always the same or just couple degree different?
2. Is Code P0101 for the Air MAF senor is bad for sure?
3. Any way can help the M1C and M2C temp cool down better? " the backseat vents always clear"

any suggestion what should I do or check next before take to dealer

M1C and M2c is F temp not C, and yes the highest for M1C was 240 degree F while M2C was 213 degree F, My inverter co0lant was 203 degree F but it drop to 195 right away, I read my temp data with SGII, when you said temp data you mean the inverter coolant or M1C and M2C? yes, the coolant inverter update frequently but M1C and M2C they hold the temp only update when the temp went up but not went down.

So 4 possible thing can be wrong, what do you thing I should change first?

Just want to make sure the inverter coolant is in front of brake fluid container right? if it is then when the engine run I can see the coolant rotating so I do believe the inverter coolant is working.

 

JD

Now I am confuse!!, the sign for the SGII for ICE coolant was FWT, am I correct JD? if it is then I have to go back to see how to setup for inverter coolant temp, JD, do you know what sign for inverter coolant temp for SGII?

Just check the

Adrian Black excel sheet, I believe FWT for ICE coolant temp, and ICF for inverter coolant temp, my mistake, I just set my scangauge with ICF, FWT, M1C and M2C, will report back how the temp will be for ICF. ​

Thanks so much for your help, for last 400 miles after I cleared out the code and it had not come back yet, I did clean out the MAF with CHOKE cleaner, if you have a BAD MAF after you clear out the code, how soon will it be come back? I just check with the dealer yesterday and it will cost about 180 for the MAF senor.
