In this Pulling Codes case, we document a U0100 code – a no communication issue with the PCM on a 2010 Dodge Caravan. With scan tools and scopes, contributor Carlton Banks diagnoses and solves the vehicle’s mysterious issues.
In this month’s Pulling Codes case, Contributing Writer Carlton Banks addresses a direct injection fuel pressure code (P00C6-Fuel Rail Pressure Low during Engine Cranking). The owner of a 2012 Chevrolet Impala states it appears to lose power at times. After the vehicle runs for quite some time, the power issue appears to go away.
A vehicle fails an emission test due to a series of codes, with misfire activity found on cylinders 2, 4, 6, 8 and 3 – and a strange metallic sound can be heard when the rpms are raised. See how Carlton Banks solves this latest Pulling Codes case.
This article addresses a misfire code from a 1999 VW Passat. It will look at a plan of attack for when a P0302-Cylinder No. 2 Misfire Activity Detected code is being set intermittently. While this code has been encountered by many, this particular failure was unique in that it allowed one to witness theory truly come to life.
Every once in a while you come across a vehicle with a P0420 code that bears mentioning. Using one of his scan tool’s features, Carlton Banks tests the catalytic converter’s efficiency.

This article will document the P0300 code for a 1996 Mercedes-Benz. A single cylinder misfire has occurred, and the technician decides to clear the code in my presence. I advised that it is a good strategy to maintain the code information for review. It’s clear that misfire activity can be challenging on some ignition systems, and I’ve found through my research that all of the car manufacturers appear to run their monitors in a similar fashion, but it’s still wise to review their service information for the differences and details of their systems.
This article documents the code P1A10-Hybrid Powertrain Control Module-Battery Disabled found on a 2006 Ford Escape Hybrid 2.3L. Code P1A10 involves a possible interlock problem with the system.
