Fuel Pump Diagnostics: Using Scan Tools
The most common diagnostic procedures for fuel pumps in the past were analog and hands on. Most fuel pump-related problems could be solved with a pressure gauge and voltmeter. Today, the scan tool is the most important tool when diagnosing a fuel supply problem.
Continental Adds New Part Numbers, Expanded Line Of Timing Belt Kits
Continental introduced 328 new part numbers to the North American automotive aftermarket during the fourth quarter of 2015, bringing the total for new part numbers in 2016 to 481. Included in the new offering of parts numbers are poly-V belts, timing belts, timing belt kits, hose and tensioners.
Diagnostic Solutions: Fuel System Pressure & Volume Checks
For maximum efficiency, modern import fuel injection systems require that fuel be delivered at a specified volume and pressure. Because the fuel injector’s job is to mix fuel with the intake air charge, it must produce a finely misted, conical spray pattern through the fuel injector nozzle. Lower-than-specified fuel pressures not only fail to provide enough fuel for combustion at larger throttle openings, but may also introduce an uneven air/fuel charge distribution into the combustion chamber itself, which usually results in hard starting, hesitation and reduced power output.
Toyota Tech Tip: Rough Idle, Surging Between 500 To 800 RPM
The owner of 2005 Toyota Avalon complains check engine light is on, rough idle and engine idle surging between 500 and 800 rpm. The technician retrieved Diagnostic Trouble Code (DTC) P0171 and P0174 (System too lean banks 1 and 2). The technician replaced the air fuel sensors on both banks and cleared DTCs. After driving vehicle for approximately one mile, all symptoms returned.
Thumping Noise At Cold Start On Honda Accord
Honda Accord owners may report a thump as the ignition switch is released from the start position or as the engine starts. This noise sounds similar to a rubber mallet striking the frame and occurs only on a cold start (the vehicle has been sitting for some time, usually overnight).
When Should Hoses Be Replaced?
Before they fail is the short answer. The long answer is it depends on the type of hose, the age of the vehicle and the application. Today’s cooling hoses, fuel line hoses, vacuum and emissions hoses, PS hoses, A/C hoses and brake hoses are all very durable and long-lived, but they don’t last forever. There are no factory recommended service intervals for any type of hose, but all automakers do recommend inspecting hoses when normal maintenance or repairs are performed.
Tech Tip: Fuel Filler Necks And Related Check Engine Light Conditions
Since the introduction of the OBD II system, manufacturers have continued to improve on the monitoring of evaporative emissions, with the complete evaporative system being under a scrutinized surveillance. Codes like P0440 to P0456 are all related to the fuel vapor control, including leaks.
