Diagnostic Trouble Codes

The Check Engine Light (CEL) can illuminate for hundreds of different reasons. While some issues that trigger a diagnostic trouble code (DTC) require immediate attention, most are for emissions related symptoms and are not necessarily critical to the safe function of your vehicle. It is best that you not wait to determine what type of code is the reason the check engine light is illuminated.

Maintenance service Codes

More automobile manufacturers are starting to incorporate maintenance codes into the vehicle’s driver information center. The maintenance required light is not the same as the vehicles check engine light. The codes indicate what scheduled maintenance services and inspections are required at the given time and mileage for the vehicle. On modern-era cars the logic/algorithm behind the maintenance schedule and indicator light goes beyond the simple time and mileage tracking of past systems. Now things such as key cycles, engine warm ups, on/off time, as well as other driving characteristics are used to determine the necessary maintenance services. CONTACT one of our team members to discuss the maintenance schedule and make plans for your specific vehicle.

Powertrain codes include the following:

P0050 HO2S Heater Control Circuit Bank 2 Sensor 1
P0051 HO2S Heater Control Circuit Low Bank 2 Sensor 1
