02 S40 1.9 turbo. 108K miles. I got a code PO107 and a PO101. I replaced the MAP sensor. I bought one new one and tried it in both locations and still get the same code. Is replacing the MAF sensor the next logical step?
I don't know what more to say than what I've already written. To sum up once again. Check engine light is on. OBD reader says PO107 as the main fault with Po101 as potential faults. Yes, replaced the boost sensors. I bought one new one. I tried it on the intercooler first. No fix. I tried it on the manifold next. No change. Still have check engine light and still get the same readings on the computer. Wife says the car "hesitates" when she tries to turn it over. I noticed it died out once at idle when I replaced the boost sensor.
No, faults never cleared. Using CAR MD which is a piece of junk but it is what I bought. It won't clear faults it just reads what the computer tells it. It has PO107 as the "failure code" and P0101 as "Potential Failure" Codes. the CAR MD trouble shooting says change the boost sensor. Unfortunately, if that doesn't fix it, CAR MD can't tell you anything else. There is no way to continue to trouble shoot. I read about the MAF by reading stuff on-line. It did not change after I replaced the boost sensor. I took a second reading after putting the new boost sensor in the intercooler and got the same exact reading as the initial. I swapped the boost sensor to the manifold location and got the same exact reading.
I had to go to church anyway. I'll wait for you to reply thanks for sticking with it.
Since my CAR MD won't clear the fault to reset the system. Is there another way to do it?
