2003 Cadillac DeVille Q&A
2003 Cadillac DeVille Question: I have PO101 code. How can I fix this problem after I have replaced MAF sensor?
If the code came back after replacing the Mass Air Flow Sensor the problem could be a faulty new sensor or a circuitry issue. Here's a good website that will desribe causes and some corrective actions. http://www.obd-codes.com/p0101 - gmc4me
