This engine code can be triggered by any one of the following:

1.) The catalyst in the catalytic converter is cracked, clogged, or otherwise damaged.

2.) The secondary O2 sensor is malfunctioning.

3.) There is an exhaust leak.

4.) The computer unit is faulty.

What is catalist?

A catalyst is a substance that accelerates a chemical reaction. It does this by lowering the activation energy necessary for that reaction to start. A catalyst is not a reactant or a product, and it does not get used up in a reaction. It is simply present with the reactants and the products and it does not change in a reaction. In an equation, it is correct to show the chemical formula for the catalyst in small characters above the "yield" arrow. The opposite of catalyst is inhibitor.

Why does a catalyst cause a reaction to proceed faster?

A catalyst lowers the activation energy for a reaction between two molecules by providing an alternative path for the reaction to happen. This way more molecules will collide with the correct amount of energy, hence speeding up the reaction.

What is the difference between an absolute threshold and a decision threshold?

An absolute threshold was seen as a hypothetical barrier that incoming stimuli must overcome before they can be perceived, it was based on the ability to pass through the threshold based on absolute judgements about a single stimulus. In the case where a person were to, for example- detect a light, the strength of said light would have to be strong enough to pass the threshold for an observer to perceive it, it was generally based on the observer's ability to detect a signal.In reality however, there is no such threshold that splits the stimulus dimension into detectable and undetectable components. Rather, a stimulus must yield a sensation that exceeds the decision criterion (beta) for even the weakest signal to be perceived, so a decision threshold is the stimulus that elicits the response or perception. The detectability and reporting of the presence of a signal- or the light- are both factors because the decision threshold must be passed and the results from the strength of the stimulus, for example the light- as well the evidence of yielding such strength, must be plausible. Only in this case, do we have correct detection of a signal.
