Why are my check engine light and trac off light both on?
If your check engine light and trac off light are both illuminated on your vehicle's dashboard, it typically indicates an issue with your car's engine or powertrain system. This could be caused by a variety of problems, ranging from a malfunctioning sensor to a more serious mechanical failure.
Potential Causes of the Check Engine and Trac Off Lights
There are several common reasons why both the check engine light and trac off light may be on in your vehicle:
- Trouble with the Powertrain Control Module (PCM) - The PCM is the computer that controls the engine and transmission. If the PCM detects an issue, it can trigger both the check engine and trac off lights.
- Faulty Sensors - Sensors like the oxygen sensors, mass airflow sensor, or crankshaft position sensor can malfunction and cause the lights to illuminate.
- Transmission Problems - Issues with the transmission, such as low fluid levels or a malfunctioning solenoid, can trigger the trac off light.
- Engine Misfiring - Misfiring in one or more engine cylinders can cause the check engine light to turn on.
- Emissions System Faults - Problems with the catalytic converter, evaporative emissions system, or other emissions-related components can also set off the check engine light.
It's important to have the issue diagnosed by a professional mechanic, as they can use an OBD-II scanner to read the trouble codes stored in your vehicle's computer and determine the root cause.
Addressing the Problem
Once the underlying issue has been identified, the mechanic can recommend the appropriate repairs to fix the problem and turn off the warning lights. This may involve replacing faulty sensors, repairing the transmission, or addressing any other issues found in the engine or emissions systems.
It's crucial to address the problem promptly, as ignoring the warning lights can lead to further damage and more expensive repairs down the line. By taking your vehicle in for diagnosis and repair, you can ensure your car is running safely and efficiently.
Why did my check engine light and trac off light come on at the same time?

What would cause check engine light to come on and off?
For instance, a loose gas cap might cause the light to turn on, but once the cap is tightened during a stop, the light could turn off again. Similarly, variable engine conditions, like changes in humidity or temperature, can cause intermittent sensor readings that trigger the light.
Is it safe to drive with the trac off light on?
While your car is typically safe to drive with the traction control light on, you should not drive it under certain conditions. If the traction control light, anti-lock braking system light, and red brake-warning light illuminate, your entire braking system may be affected.
