RX400H Check Hybrid & DTC P010A when A/C ON

Recommended Posts

I have kind of weird problem with my RX400H 2007. When I turn my air con on, I get Check Hybrid and Check VSC message displayed with check engine light, traction light and red triangle. Scanning tool displays P010A code (Mass Air Flow (MAF) B Circuit Malfunction). Just to make sure, I ran vehicle for about a month without turning on A/C (blower was on most of the time) and no errors. When I turned on A/C today, same error came up. I’m unable to understand what air con and MAF circuit to do with each other. The vehicle keeps running fine when error comes but doesn’t start after turning off, until code is cleared or battery terminal is removed and replaced. I’ll really appreciate if anyone can help me solve the issue.
