Debris, Melted Insulation Cause Two Codes to Set
About two months ago a customer brought in his 2006 Ford E350 Econoline van equipped with a 5.4L engine and a 4R75E transmission for an evaluation. His concern was that the check-engine light was on and the transmission seemed to shift hard at times. We always begin our evaluation with a battery and charging system test with a Midtronics electrical system analyzer, and we scan all modules for codes using a Snap-on Verus Pro if we are not using an OE scan tool. After a quick visual inspection of the vehicle and checking the engine oil level, we will proceed with the road-test.
