Hello everyone,

I recently had a fault code that my MAF was giving out high signal, i changed the MAF new one hitachi Friday and I cleared the code, ran the scan again and tested the value they are good 4.96 -5.11 while idle. Saturday the check engine light came back on so I scanned it again and I got a whole set of different fault codes.

17965 - charge pressure control
P1557 35-00 Positive Deviation
17861 - Exhaust Gas Temp Sensor 1 (G235)
p1453 35-10 Open or Short to plus - intermittent
17545 - Fuel Trim Bank 1 (add)
p1137 35-10 System too rich - intermittent
17547 - Fuel trim bank 2(add)
p1139 35-00 system too rich

Can someone please tell what the best way to go about solving these? Any idea on what might have caused these too?

Thanks,
Kazim

If you are getting between 4.96-5.11 g/s at idle for a MAF reading then you have a problem... It should be hovering around 3 g/s.. Something is causing excessive engine vacuum and that usually means there is a restriction around the airbox... Make sure the plastic pieces that go from the airbox to the rad support are not bostructed with a mouse nest or something...

i took the whole intake system out, from the plastic vent leading to the intake box, all clean, took out the air filter and its all good K&N then the vent connecting the MAF to the Y shaped pipes are clear. reading that i got from the MAF was 4.28 was the lowest it got. what else should i do to troubleshoot now

thanks
