4 Signs Your MAF Sensor Is Failing | AutoFixCentral

Hey! I brought my Volvo V60 D4 2.0 from '15 to a couple of mechanics after it started losing power at low RPMs suddenly while driving in hot weather, in hills/mountains for a few hundred km. I've checked Boost Charge Valves, cleaned MAP sensor, Boost sensor, visually checked hoses for leaks (I hear no difference). The readings I get seem alright/normal. Regardless of the gear, at low RPM I just see bad performance, like no horses are home. Above ~2.500 RPM I get all 181 horses released in one go. I got error codes, P2262, while a few more were present, I didn't see them. First mechanic immediately said "New low pressure turbo, aka new turbo, money plz" within 10 minutes with the computer on it - didn't even drive it. This guy said the other codes happened because of P2262. Second mechanic took it for a test drive, put the computer on it and said it could be the MAP sensor - after I explained it had been replaced, they said "MAF sensor then". These guys said P2262 could be triggered by the bad MAF. Is it normal that a bad MAF sensor will only and always affect the low RPMs? I think it's quite pricy and I would like to make sure before buying.

Have them check that there are no loose hoses, wiring, and that your turbo is working fine... Doesn't sound like a bad MAP sensor but your mechanics will be in better position to decide.

​@@autofixcentral Thank you for your response - I wish they would actually test and do more. I'm pushing them to, but I've talked to 3 different ones and all are like "ughff, tough one". Appear to be no loose hoses, nor wires. I'm not sure how to verify whether my turbo works. A mate suggested unplugging the battery and leave it for 10 mins, then connect it again and immediately drive. If it's a bad turbo, the problem would be there immediately, while if it's a bad sensor it would take a minute or so before the fault arises again. I have yet to try this tho
