90LS400Lexus Posted August 7, 2004 Share Posted August 7, 2004 I am thinking it is a "MAP"? sensor, but not sure. Something on my car appears to have been replaced with a used one, because it has red writing on it. What exactly is this? Thanks in advance.

lex4me Posted August 7, 2004 Share Posted August 7, 2004 Looks like the mass airflow sensor. Quote Link to comment Share on other sites More sharing options...
blake918 Posted August 7, 2004 Share Posted August 7, 2004 Yeah, that's the mass air flow sensor. It probably broke somewhere along the past 14 years and was replaced with a used one. I'd have done the same since a new one is about $900. ;) Quote Link to comment Share on other sites More sharing options...
SKperformance Posted August 7, 2004 Share Posted August 7, 2004 that is yourmaf sensor which gauges the amount of air flow to the engine Quote Link to comment Share on other sites More sharing options...
