I took my car to mechanic to fix an egr flow code, P 0400.\u00a0 After code was fixed (new egr valve and solenoid) salesman told me another code popped up\u00a0 and it was the mass air flow sensor.\u00a0 He said the car would start and then die.\u00a0 He said the reason the mass air flow sensor code wasn’t on before I brought car in was because the computer compensated for the 0400 code and that’s why there was no mass air flow sensor code.\u00a0 Once the egr flow code, P 0400 was fixed the computer registered the mass air flow sensor.\u00a0 He asked me what I wanted to do.<\/p>\n
Well at this point my options are limited ( I was waiting at garage) so I said fix it.\u00a0 The part cost $300 but no labor was charged.\u00a0 The car was running fine prior to bringing car to garage other than P0400 code light on.\u00a0\u00a0 If the computer compensated for the mass air flow sensor by making other adjustments (thus enabling the car to operate fine) in the engine system why wouldn’t it be able to after the new egr valve and solenoid were replaced?\u00a0 Something doesn’t sound right?<\/p>\n
Also as the car was being worked on I needed something out of the car so I looked under the hood to see how they got to the egr valve.\u00a0 While looking at the engine the mechanic, a younger adult around 24, said he cleaned and pointed to the mass air flow sensor.\u00a0\u00a0 At the time I didn’t know what it was and thought that was nice of him.\u00a0\u00a0 Now I looked it up and realize he pointed to the mass air flow sensor.<\/p>\n
I already paid for the part and they didn’t charge labor.\u00a0 Which is odd because I never seen a mechanic work for free and wouldn’t expect one to.\u00a0 Can anyone tell me if the mechanic messed up the mass air flow sensor?<\/p>\n
Thanks<\/p>\n
