jerryparks Posted July 13, 2022 Share Posted July 13, 2022 Need advise on above problem. Code says I have problem with ma's air flow unit. Is there anything else I need to check ? Recent timing belt and water pump has been chamged. Could the car need tune up ? Quote Link to comment Share on other sites More sharing options...
RX400h Posted July 13, 2022 Share Posted July 13, 2022 Have you tried cleaning the Mass Air Flow sensor? CRC has a spray can for this purpose. Quote Link to comment Share on other sites More sharing options...
paulo57509 Posted July 14, 2022 Share Posted July 14, 2022 What is the exact code stored (Pxxxx)? Did this issue and code start out of the blue/after the timing belt change? Who did the work? Did spray cleaning the MAF solve the issue? Inspect the electrical connector to the MAF. Quote Link to comment Share on other sites More sharing options...
