Can fuel injectors cause O2 sensor code?
The real problem may not be a bad O2 sensor, but possibly be an engine vacuum leak, low fuel pressure or dirty fuel injectors that are causing the engine run lean. An engine misfire, leaky exhaust valve or a leak in the exhaust manifold gasket that allows air into the exhaust may also cause this type of code to be set.
Can injector cleaner damage oxygen sensor?
Fuel additives and injector cleaners that are labeled as “oxygen sensor safe” may be used in sensor equipped vehicles. Use of additives not labeled as “oxygen sensor safe” can damage your oxygen sensor.
Does fuel injector cleaner clean O2 sensor?
Can I Just Clean My O2 Sensor? The short answer is that our strongest gasoline fuel additive, B-12 Chemtool Total Fuel System Clean-Up (part #2616), and a good tune-up might indirectly solve your problems. There are no true oxygen sensor cleaners that are safe to put through your engine.
Can a bad O2 sensor cause a Toyota Corolla to fail?
Often enough, there won’t be any noticeable signs of a bad oxygen sensor. You’ll go to get an emissions check done, and your Corolla fails the test. Without a check engine light, it can be tough to lock down exactly what would cause the vehicle to fail, but oxygen sensors are one of the more common causes.
Why does the Check Engine light come on on my Toyota Corolla?
Oxygen sensors can change the way that your Corolla’s engine runs. Most of the time, the check engine light will come on. It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test.
Where is the oxygen sensor in the engine?
An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.
What are the symptoms of an oxygen sensor going bad?
One of the most common symptoms that an oxygen sensor has gone bad is exhaust that does not smell good. The smell is often described as “rotten eggs” or sulfuric. Either way, like with rotten food, “the nose knows”.
