How Do You Reset A Toyota Hybrid Battery? Contemporarily, hybrid vehicles have automatic systems that read warnings from different components to diagnose and alert you of specific issues. However, varying reasons usually trigger these pre-programmed warning systems; since the Toyota hybrid explicitly combines an internal combustion engine and electric motor as power sources. Its system serves as a regulator of these power sources. Although failure could occur due to some factors, and the warning light is triggered.

Be it as it may be, the system will surely malfunction if the warning light results from some issues with the battery. So, you could detect a lousy battery if the Toyota’s hybrid battery charge fluctuates. This fluctuation could empty the battery, and you might need to replace it and reset the system as quickly as possible.

Interestingly, this guide will address and offer solutions to these typical queries, ranging from; what would cause a hybrid not to start, why is my Toyota hybrid not starting, what is the most common problem with hybrid cars, how do you reset a Toyota hybrid battery and more.

Why Is My Toyota Hybrid Not Starting?

The Toyota hybrid is a reliable vehicle but a complicated machine. So, the problems below would cause your Toyota hybrid not to start.

  1. Key Fob Battery – The Toyota hybrid usually starts with a key fob, so if the key fob is faulty due to a bad battery. Then your vehicle won’t start.
  2. Weak Battery Issues – Discharged 12-volt battery or corroded battery terminals could be a severe issue for your vehicle not to start. Check your battery terminals, identify discharged batteries, and replace them immediately.
  3. Blown Fuse – Always check your fuse box since a faulty fuse could cause your vehicle not to start.
  4. Ignition Issues – Faulty spark plugs which don’t create a spark would cause the vehicle not to start.
  5. Overfilled Engine Oil – The excess amounts could get into the combustion chamber, resulting in issues with your vehicle not starting.
  6. Evaporating Emissions System – This problem occurs in system failure or leaks due to faulty valves or lines. Ensure you have regular hybrid maintenance to prevent this evaporating emissions problem. 
  7. Lousy Oxygen Sensors – The oxygen sensor regulates the quantity of unburned oxygen in the vehicle’s exhaust. If, over time, it fails, it could cause a secondary problem due to high oxygen levels in the exhaust system.

What Is The Most Common Problem With Hybrid Cars?

The most common problem with hybrid cars is battery cell failure. The hybrid’s battery powers the electrical systems; therefore, if any issue emanates from the battery, there is a tendency for the system to fail. Similarly, failure of the 12-volt battery would also constitute malfunctioning of the internal combustion engine and the regenerative braking system in hybrid vehicles.

  • Allow the connection for about 5 minutes.
  • Run the engine of the vehicle to boost about 2,000 RPM as you depress the gas pedal gently.
  • Start the hybrid vehicle and make sure the READY light is on using the push-to-start button. If the READY light doesn’t glow, charge for an extra 5 minutes and try starting the vehicle.
  • Disconnect your connections in a converse manner starting from the negative terminals and cables and to the positive wires.
