Does your truck seem more sluggish than usual, possibly lacking power when passing a slower vehicle or when going up a hill? Has a mysterious dashboard light come on, causing you to worry? With winter on its way, it would be smart to schedule a tuneup, including a diagnostic test, to make sure your truck can perform its very best.
What does a diagnostic test tell you? Today’s modern vehicles have computer processors, microchips and sensors. Beyond your steering wheel lies a dashboard, called the On-Board Diagnostic system or OBD, that shows detailed information on your vehicle’s operation and performance. In short, it’s a system that allows the vehicle to monitor and communicate via the car’s internal computer system. OBD is essential in monitoring major engine functions, electrical condition, and measuring vehicle emissions.
A qualified technician utilizes the vital information that is stored there to help determine what mechanical or electrical processes have failed in order to repair your vehicle. A diagnostics test can reveal problems associated with the engine, transmission, oil and gas tanks, exhaust system, and other systems.
With the use of a specialized computer linked to your vehicle, your mechanic can pinpoint exactly where a problem may exist, producing the fault codes which are stored in the vehicle’s memory system. By quickly identifying the cause of a problem, the right repairs can be made before a bigger problem occurs.
It’s important to note that driving for an extended period of time with any lights illuminated on the OBD, can cause further damage resulting in costly repairs. If at any time the lights are flashing on the dashboard, avoid driving the vehicle and take it to a trusted technician immediately for inspection.
During a diagnostics test, a trusted technician uses a specialized computer scan tool to test the system and decipher the codes. Here are 4 common codes that our qualified mechanics see on a weekly or even daily basis:
1. Faulty Oxygen Sensors
Oxygen sensors monitor the amount of oxygen in exhaust, allowing the car’s computer system to adjust the fuel mixture for better fuel economy and lower emissions. When an oxygen sensor malfunctions, drivers may notice a dip in their gas mileage or random stalling.
2. Engine Misfire
Misfires are the result of dysfunctional cylinders. Misfires detect the amount of fuel each cylinder requires. One of the common symptoms is shaking while idle. This issue can also result in loss of fuel efficiency.
3. Exhaust Gas Recirculation
The EGR controls the engine’s release of dangerous emissions by recirculating the engine’s exhaust back into the engine cylinder. This helps lower your engine’s combustion temperature for a reduction in oxides of nitrogen emissions. Problems occur when carbon builds up. Often this is due to lack of oil changes or infrequent driving. Associated symptoms include a reduction in power, acceleration, and decreased fuel efficiency.
4. Catalytic Converter
A catalytic converter is a device that converts toxic gases and pollutants in exhaust gas to less toxic pollutants. When the converter becomes contaminated, the tailpipe emissions can increase. The cause could be an old engine or a leaking coolant.
