Bpc5761568908860 Posted November 6, 2016 Report Share Posted November 6, 2016 i have a 2000 s40. every few days it throws a TPS code and a MAP sensor code. however ive replaced the tps sensor and on my OBD2 scan gauge it shows that the MAP is sitting in normal pressure zones. could it be a bad MAF sensor? throwing off both the throttle and MAP codes? i cant figure it out! any advice would be great 0 Link to comment Share on other sites More sharing options...
1clean00 Posted November 7, 2016 Report Share Posted November 7, 2016 Is there any rhyme or reason to the codes? Cold start vs. hot restart? Morning, daytime, night, etc. Difficulty cranking at all? If it is totally random i'd look at the wiring and connectors more carefully and make sure that you're making good connections. If you can reset codes with your scantool do so and see if they come back. I would try to clean the MAF also and reset codes. Link to comment Share on other sites More sharing options...
Phixion Posted November 8, 2016 Report Share Posted November 8, 2016 I ditto cleaning the MAF. A dirty one can cause all sorts of endless chases to the root of the problem, a dirty MAF... Link to comment Share on other sites More sharing options...
catback Posted November 15, 2016 Report Share Posted November 15, 2016 Take a good hard look at the hose between the Idle Air Control (IAC) and the Intercooler. Sorry to be so late to the party. Link to comment Share on other sites More sharing options...
