How do you reset engine light on jeep liberty diesel

From what I read in the manual it is the catalytic converter. A misfire that could damage the cat.

No, oil level does not cause the check engine light.

The engine computer controls the check engine light.

Some have a safety switch to prevent engine damage that cuts off fuel supply as soon as engine oil pressure drops to an unsafe level

The oil level will not cause the check engine light to come on.See related question below.The oil level will not cause the check engine light to come on.See related question below.

It looks like a little yellow engine.

Scan tool, will give you a trouble code as to why the computer turned the check engine light on.

The check engine light is reset with a scan tool after repairing the failure that caused the code.

1) the engine oil level is low 2) the engine oil is old - making it very thin, especially after the engine warms up. Likely the oil light is doing its job and calling your attention to the level and condition of the engine oil.

Check to coolant level in the coolant recovery tank and radiator when engine is cold

There are dozens and dozens of causes for the check engine light to stay on. You need to have the computer checked for codes to know possible causes.

The engine is overheating. The check engine light is not on because you have no problem with the emissions system which this light monitors.

Have vehicle scanned to determine the problem

if the coolant light is flashing red it means it's overheating (DO NOT DRIVE), check coolent level "if level is fine", it may be your thermastat. if coolent level is low check your coolent hoses. (allow engine to cool before checking)

Have it checked for codes with a scan tool. There are pages and pages of causes for a check engine light.

Oil level or pressure will not trip a check engine light.

Your bad muffler might be part of the reason your check engine light comes on. Usually, your bad muffler causes something else to go wrong and that causes your check engine light to come on. Problems cascade.

disconnect your battery for 45 secs and reconnect

You reset it with an OBD2 scan tool after it is repaired.
