Toyota EGR Valve
No matter how your Toyota EGR valve is cobbled up, the fact which carries weight is that your Toyota EGR valve is vital to the ignition and emissions systems of your TOYOTA. Mechanical EGR valve is to vintage Toyota models like Toyota AA, Toyota G1, Toyota SC, Toyota BA whereas electronic EGR valve is to latest Toyota models like Toyota Corolla, Toyota Camry, Toyota Land Cruiser and lot many to mention in this category.
Different issues with Toyota EGR valve
- The Toyota EGR valve is crafted in a way to open and close at a fixed interval of time and is not suppose to open or close. If it is left opened it will lead to rough idling of the engine. On the other hand, if it is closed the temperature of a combustion chamber rises immediately resulting into a knocking engine.
- Both the situation i.e. open or closed Toyota EGR valves lead to different symptoms to intimate you for an immediate replacement or servicing. If left open, these valves may involve bizarre operation of an engine while a closed valve is followed by a bang due to smoke and ascending level of power loss.
- A closed EGR valve may give birth to severe issues in the exhaust pipeline.
- Flue gases create Turbos meant for boost. By any means, if high temperature of flue gas sustain for a long time, then due to excessive heat the lubrication may fail resulting into a seized Turbo.
- Due to leakage of oil drops in a circuit, your Toyota EGR valve may get blocked. When mixed with smoke particles, it becomes greasy or can say "pulpy". The deleterious valve hinders flow of air, hence effects the functioning of a valve.
- A jammed valve and failed program of an EEPROM results in to power loss while jaunting along with a nudge when stepping on a pedal.
Symptoms of a decayed/ degrade Toyota EGR valve
- Violent shaking, shuddering and lurching of a car engine.
- Horrible acceleration and rough idling of a car.
- Knocking of EGR valve or sometimes a spark knock.
- Carving of the engine timing.
- Inefficient combustion of fuel air mixture.
Things you should/ should not do to protect your Toyota EGR valve
- Always use 100% synthetic oil like Amsoil, Elf Excelium, Castrol Magnatec, Shell helix… or any as recommended for Toyota engines which reduces the amount of carbon deposits and also stays cleaner and quieter. As you are aware of a fact that the viscous characteristic of oil changes with temperature that is why it is recommended to use 5W-40 in cold climate and 10W-40 in hot climate.
- Do not forget to remove the chunks of carbon deposited in-and-around the exhaust gas entrance with a pointed object like a dentist's pick just after soaking it in petrol for 24 hours.
- If your Exhaust system involves gasket, then do not forget to replace it when required.
- You must clean the valve and reprogram the EEPROM at regular interval of time.
- Do not clean your EGR valve with gasoline/ solvents as they may badly affect the diaphragm.
Reduction in unnecessary engine emissions and lessened engine knock can be obtained by a perfect Toyota EGR valve, procured from a trusted auto-part manufacturer and is sure to be of advanced quality and excellent craftsmanship.
