Can a vacuum leak cause an oxygen sensor to fail?
Unfortunately for the ruined oxygen sensor the vacuum leak was so severe that the power train control module could not compensate. As mentioned above vacuum leaks can cause an extremely high combustion chamber temperature and post-combustion chamber temperatures as well.
Why is my fault code and O2 sensor melted?
In fact, the fault code and melted sensor meant that the problem was a lean condition that needed to be resolved. A lean mixture can cause very high combustion chamber temperatures and can also melt spark plugs. If you find a melted o2 check the spark plugs also.
How can I find out if there is a leak in my vacuum?
Any search for vacuum leaks should start out with one important tool: a vacuum hose diagram. This is sometimes printed on a placard in the engine bay. If not, look one up in the service manual or consult an online service such as AllData.
Where does a vacuum leak in a car come from?
With some vehicles using dozens of vacuum hoses and the potential for cracks in multi-part intake manifold systems, there are plenty of places for leaks to crop up. The ducting between the throttle body and the MAF sensor is often 3-inch-diameter rubber that can also degrade and develop leaks.
How can I find the trouble code on my Saturn?
To retrieve trouble codes, turn the ignition key to the “on” position with the engine OFF. The Check engine light will flash many short blinks. The total number of blinks equals the code number.
How does the Check Engine light work on Saturn?
The Check engine light will flash many short blinks. The total number of blinks equals the code number. For example, flash,pause, flash,flash = code 12.If more than one code is stored, the Check engine light will flash the codes in sequence (lowest to highest) with a pause between each code.
What does p0174 mean on a Saturn L300?
P0174 basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). Bank 2 is generally the side of the engine that doesn’t have cylinder #1. P0171 means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust).
What are the codes on a Saturn L300?
I have a saturn L300 sedan V6 with the codes P0421,P0431,P0171,P0174 all on. I have someone say that an engine temp control sensor might be the cause Clicking this will make more experts see the question and we will remind you when it gets answered.
