TOYOTA RAV4 2004 NO POWER BUT ENGINE WORKS SERIES

These were just some of the most common ones.Ī dirty throttle body can lead to stalling in your Rav4. There are many other sensors that can cause your Rav4 to stall. If one of them has gone bad, then it could lead to stalling. The ECU uses this data to make adjustments to the air/fuel mixture.

Oxygen Sensor– The oxygen sensors measure the exhaust gasses after they exit the combustion chamber.

Here’s more on diagnosing a bad mass airflow sensor. When they go bad, your Rav4 may not be letting in the right amount of air for a quality air/fuel mixture.

MAF/MAP Sensors– These sensors are responsible for air measurement.

Here’s a great article on diagnosing a bad throttle position sensor from cars direct. The first is that by limiting the amount of torque when you push the gas pedal for a second or two, engine life is increased by reducing the stress on it during takeoff. These days the computer handles all of that. It is very rare these days to be actually directly controlling the amount of fuel and air entering the engine directly. This sensor is responsible for telling the engine how much air and fuel to allow in.

Throttle Position Sensor– The throttle position sensor is typically located on the gas pedal.

When one of them goes wrong, it can lead to stalling for sure. The ECU then uses this information to adjust the timing, air fuel mixture, and more.

Your Toyota Rav4 uses a series of complex sensors to report what is going on to the ECU. Here’s more on timing chain jumped symptoms. If that happens you are going to go from misfire to un-drivable. Just know, that if it jumped a tooth, it’s only a matter of time before it jumps more or breaks all of the way. Timing Chain Jumped– If your timing has jumped a tooth or two, it’ll definitely stall out.If there is a VVT issue, it’ll often throw trouble P0010, P0011, or other related trouble codes. This allows for the engine to be in the “sweet spot” of power or economy depending on how hard you are pushing the gas pedal. VVT Problem– Many modern engines are equipped with Variable Valve Timing.Here are some of the more common causes of an engine timing problem: If your Toyota Rav4’s engine timing is off, it’s going to stall out, misfire, and altogether not run properly. This can be caused by the fuel pump or fuel filter. When it asks for a lot of fuel, instead of taking off, it stalls out with the demand. Not Enough Fuel– The fuel pump may not be able to provide the fuel pressure needed for the engine to run properly.Here’s more on Toyota Rav4 bad fuel injector diagnosis. Or, it just may not be able to properly atomize the fuel anymore. Bad Fuel Injectors– If the fuel injection system is allowing too much or too little fuel into the combustion chamber, than your Rav4 will stall out.Usually it’ll be a bad sensor reading, vacuum leak, or other problem that’ll cause the air/fuel mixture to be wrong. Air Fuel Mixture– If the air/fuel mixture is off, your Rav4 can stall out.

Here’s a good article on all the symptoms of bad gas. If there were no other symptoms and suddenly you find that the vehicle is running very rough, bad gas could certainly be the problem. Water in the gas tank can also cause gas to not fire properly.

Bad gas- can cause an engine to stall out.It needs them in the right quantities and intervals, or it won’t run right.įuel issues are one of the most common reasons that a vehicle would stall out, that includes your Toyota Rav4. Remember, a vehicle needs air, fuel, and spark to run. Here are some of the issues that cause the Rav4 to stall out. If you don’t own/want to buy a scanner, most local parts stores will run a scan for you at no cost (they want to sell you the parts). They are often specific enough to get you all the way to the problem, or pretty darn near. Trouble codes are always a great place to start diagnosing problems on today’s modern computer controlled vehicles. Stalls can happen at any time, and it can be incredibly jarring when it does happen.īefore troubleshooting any automotive issue, including stalling issues with the Rav4, make sure that you check the vehicles trouble codes with an OBD2 scanner. The most challenging part of diagnosing a stalling problem is reproducing the conditions that led to the stall in the first place. One of the most common issues your Toyota Rav4 is likely to develop is a stalling problem.
