Spark Plugs: The Lost Art Of Gapping
With modern fine-wire spark plugs, you should not measure the gap unless instructed by the manufacturer because you could damage the center electrode. The majority of these plugs come pre-gapped from the factory, but it is still a good idea to inspect the new spark plugs for damage or defects.
Oil And Carbon Deposits
Gains in power and fuel economy have been realized with direct injection and turbocharging.

Dodge Tech Tip: MIL Lamp From Oxygen Sensor
If the 2010-2014 Dodge Ram 2500 or 3500 has any O2 sensor-related DTCs stored, pending or active, perform the repair procedure. Both oxygen sensor connectors should be removed and new connectors with pigtails installed. The pigtail splice points should be staggered to eliminate bulk in the harness.
Honda Tech Tip: Low Tire Pressure And TPMS Indicator On After Recent Tire Replacement
The Honda CR-V uses an indirect TPMS system that uses the rolling circumference of the tire to determine the pressure in the tire. Differences in sidewall construction and weight of a replacement tire can cause the rolling circumference to change if a single tire is replaced.
GM Tech Tip: Power Steering Fluid Leak At Reservoir Or Reservoir Connection
When diagnosing power steering fluid leak conditions, the technician may find a heat-damaged fluid reservoir. When a power steering reservoir or reservoir seal is damaged, it’s important to make sure that potential associated issues are addressed.

TPMS Radio Frequency Theory And Operation
A typical wheel-mounted TPMS sensor will transmit data about tire pressure and temperature. Newer, tire-mounted models can also gauge acceleration and, in some cases, the direction that the wheel is spinning. Some systems display tire pressure by location on the instrument panel, but most do not.
