Reset check engine light on Kenworth T660/T680/T880 Trucks

The truck industry had never been ameliorated before the commencement of Kenworth’s biggest draw in the history of truck vehicles. It has been patronizing this industry for more than a century. Kenworth has become an iconic brand in the early twenties. It is a famous brand that started walking in the industry in 1912. Kenworth has designed some outstanding elements of trucks. The popular tradition of using superior aerodynamics in most trucks has changed the horizon of thinking in this arena. Some of the trucks are designed to have the smoothest air controlling system, the settings towards an industry standard for aerodynamics. Kenworth is the brand that has revolutionized modern-era truck systems. 

Short overview: Kenworth T660, T680, and T880 heavy-duty trucks

Over the years, Kenworth has introduced some authentic elevations of trucks. Now it is time to look into three of the greatest this industry has seen. Let us gather some knowledge about the most promising creations by Kenworth. 

Kenworth T660:

The Kenworth T660 is a perfect truck for having the line and regional haul, bulk haul, pickup, and delivery on the go. The Kenworth T660 is the most highly anticipated and evolving tight aerodynamic route conventional truck. Kenworth has added the mechanism of having the least fuel consumption in this truck. The core feature of this truck is, 

  • It has a vigorous Cummins ISX, 485-hp and 2000 rpm, and 1650 lb-ft of torque 1200 rpm main engine that can incapacitate a larger amount of weight. 
  • The vehicle’s halogen headlights, evaluators learned, throw light four times further than previous ones, and bulbs can be replaced without tools. The high-intensity xenon lamps are a super-bright option. 
  • Kenworth air suspension system is something very much obvious in metering disabilities. The sheet-metal durability; and rubber weatherstrips are mounted to doors to reduce damage from the entry or egress system.
  • The ancestral transmission, Front axle, Rear axle, and the Antilock wheeling system can be the most dramatic synchronization between the adverbials.

Kenworth T680:

The T680 is best known for its aggressive aerodynamic design and a rich combination of craftsmanship. The most intuitive controlling feature. The most superior and spiraling combustible aerodynamic long-haul feature has made it a hulk in its specific genre.

  • It has the Kenworth Idle Management composure, which is architected for destroying the insurgence from the off-duty temperature controlling system. 
  • It is incorporated with a furious TruckTech+ technology. The T680 has high-tech maximum fuel efficiency, and the interior and extra compartments’ craftsmanship is usually amazing. The ergonomic solution all have combinedly derogated the excellence of this truck.
  • It has a massive 19″ side extenders chassis, rear and front sleeper, front wheely closeouts, and robust tandem fairings in its interim moveable compartments.  
  • The Optional aerodynamic enhancements are associated with solid wheel covers. The most enticing feature of the truck is the PACCAR engine which has a reputation for supreme intelligent shifting of drivability.   
  • The sleeper control panel, driver control maneuvers, sleeper environment, and interior sense of ABS have all been incorporated into the T680 model.

Kenworth T880:

  • The most eye-grabbing feature of the Kenworth T880 is the Paccar MX-13 engine. You can locate it most probably under the hood. The working capability is a maximum of 500 hp, and the maximum torque is about 1,850 lb-ft.  
  • It has a classy, bold, and heavy-duty appearance. It has a bone-staggering box bumper, and you can enjoy the maximum excellent forward visibility through the sturdy one-piece windshield.  
  • Another tremendous edition is the Diamond VIT T880 cab that gives you ultra comfort on a long-distance journey. It has a massive 15-inch digital display that covers most of the signals on a single screen.

  • The torque-assisted steering wheel and electric motor control system give that extra vibe in aggregating the gesture while driving the vehicle. 

What are the reasons for blinking check engine lights on Kenworth trucks?

There are tons of causes of producing a sudden CEL in Kenworth T660, T680, and T880 trucks. Here I am mentioning some of the valid ones, 

  • A fault in the oxygen sensor can be a tremendous coefficient of emanating the CEL in the Kenworth T880, T660, and T680.  
  • It is imperative to have a colloquial amount of oxygen in the exhaust to inject usable fuel into the engine. The CEL also comes in daylight if the fuel economy is getting plunging. 
  • A loose gas cap is one of the biggest reasons for bringing the CELL into action. If vapor is leaking somehow, then it can trigger fuel sensors.
  • A faulty catalytic converter is the biggest culprit for showing the CELL in the Kenworth trucks. A bad spark plug is as well as the biggest reason for emanating the light.   
  • The CEL can advance into the system if the ignition coil is damaged badly. Due to high temperatures, the spark fails to generate itself. A bad spark plug can be a threat to the cylinders as well as the engines. 
  • A defective mass air flow sensor can also yield the CEL. If this sensor fails to detect accurate airflow, then it can be a disaster for the Kenworth truck.
  • Disastrous leakage in the vacuum hoses related to the EVAP system can also produce the CEL in the Kenworth T660, T880, and T680. 
  • A defect in the exhaust gas emission recirculation valve is very much alarming for Kenworth trucks. The combustion process can suffer if this segment is not working in a simple manner.

Kenworth T660, T680, and T880: How to Reset the Check Engine Light

It is very much significant to appease the CEL. Otherwise, it will inevitably create a big imputation on the truck. You can find a knob on the right side of the steering wheel. The ECM must be in a recession as the CEL is in daylight. The internal wiring and harness could be facing something irreversible, so it needs to be in a stable condition to mitigate the issue completely. When you find the diagnostic trouble codes (DTC), press the knob once and for all. Then it will initiate a larger home for turbulence inside the truck. Another typical warning indicator is the diesel particulate filter (DPF) light, which is harmonious with the CEL and harmonious with all the trouble emanating effects. You should Check the air filter for dirty deeds.

Try to reset the ECU for a momentary malfunction indicator. The battery might be in need of some repair because an unhealthy battery is always a threat to the truck’s main engine. So remove the negative battery terminal and restart the engine. Take a test drive and check if the lights go off. 

Reset CEL:

First, park your Kenworth truck at a decent place where the servicing can be done easily. The auto garage is the best place for servicing the truck because it needs a spacious site for repairing trucks. Then turn the ignition on and make an attempt to restart the truck. Put the transmission of the engine in a neutral position. Put a moderate gesture on the brake panel and see if it is working or not. Sometimes the truck can not recognize the ignition key as it is dealing with some internal issues, or maybe the key is not compatible with the truck. Regenerate the parking brake and see the condition of the vehicle. Then hold and free the parking brake to readjust the mechanism. Consequently, press and release the clutch pedal of the Kenworth vehicles. Push the regeneration button at the dashboard and check if the CEL is still 

Should You Continue Driving the Kenworth Trucks If the Check Engine Light Comes On?

If the engine light comes on in daylight, you should immediately stop driving the truck. The vehicle’s engine doesn’t need to sputter on the spot, but it has the worst consequences in the near future. If the check engine light blinks continuously red, it is a must to stop the vehicle and take it to the garage because the truck is facing some cynical issue. A glowing red engine light determines that the vehicle must be facing some imminent danger or a severe breakdown. You should never drive the truck if the CEL is illuminating continuously. If you ignore the CEL and continue driving, then it may cause irreparable damage to the truck.
