code p0101 p0131 p0137 p0151 service eng light has been on for 2000 mi. Initially the light did not stay on. When I started the van on the morning after it did not come on for days. It came on again under load after warming up. In time it started getting more steady on. Now it just stays on.The van has 171,000 mi runs smooth but bad mpg.
17.1 average. The 02 sensors appear to be in good condition and newer than the van, but at least 2 years old. The voltage at the Mass or Volume Air Flow plug is correct. Thank you.
