A GROUND WIRE OR ELECTRICAL HASSLE
Does your Toyota Highlander shuts off while driving? Don’t forget to have a look at your electrical system, if it’s a ground wire, for example, which can bring about a short circuit, or a totally damaged electrical circuit that can no longer carry electricity. This is one of the most difficult causes to detect… We advise that you try to locate a “burnt” part for the ground wire, which would present that an electric arc has created between a cable and the bodywork, however you will surely have to contact a professional to solve this problem.
IDLE ACTUATOR
The goal of this part is to control the engine idle speed of your Toyota Highlander. If your Toyota Highlander engine unit stops suddenly when you’re at a standstill, such as at a red light, check the level of wear on your actuator.
THE FUEL PUMP
One of the most logical motives, without fuel, the engine stops running. Sometimes, over the years, the fuel pump filter can become clogged or the fuel pump is weak and no longer pumping. Either way, your Toyota Highlander could stop while driving.
FUEL INJECTION SYSTEM
Same reflection as seen before, however, in this situation it is the last phase of the fuel intake into the engine. Seized injectors, a defective injection pump or sensor and your Toyota Highlander can go out of service or completely disable your fuel injection. An injection problem will generally appear when the fuel injection is hot.
NEIMAN PROBLEM
A neiman, principally concerning its ignition switch, will often bring about you trouble and bring about your Toyota Highlander to stop while driving. This element, which is necessary for starting your motor vehicle, as well serves as an anti-theft protection, which will prevent your Toyota Highlander from running normally if it fails.
IGNITION COILS (PETROL ENGINE ONLY)
The penultimate main explanation an Toyota Highlander stops while driving is the ignition coil. This origin is just relevant for petrol cars since the engine runs by explosion and not by compression. In case your coils are too worn out, they will no longer spark. Look on that side.
BATTERY / ALTERNATOR
Finally, it is as well possible to be the victim of a tired battery or a damaged alternator. In both cases, the lack of energy stored inside the battery will prevent your Toyota Highlander from running as it will no longer be able to power the main parts of your engine unit.
