Sentences with phrase «lean fuel condition»

This relates to a lean fuel condition which can be caused by many different things such as: Intake air leaks Faulty front heated oxygen sensor Ignition misfiring Faulty fuel injectors Exhaust gas leaks Incorrect fuel pressure Lack of fuel...

As you may know know, a misfire can be caused by many different things ranging from a faulty ignition coil, to bad spark plug wires, bad spark plugs, a faulty crankshaft position sensor, a lean fuel condition which could be...

Not exact matches

At idle if there's more volume than calibrated for, the AFR / O2 sensor will see a lean condition and the ECM adjusts fuel trim to compensate.

Since the intake manifold pressure is directly measured to calculate the intake air volume and decide the amount of fuel to inject, a vacuum leak theoretically can not contribute to a lean condition like this.

This problem can actually affect the gas mileage as you will be sucking in oxygen at the leaks which confuses the O2 sensors into telling the computer to dump more fuel (it reads a false lean condition).

A clogged fuel filter can restrict fuel volume causing a lean condition, and set random...

Too much air compared to fuel will cause a lean misfiring condition.

P0420 could be due to a variety of faults including even a fuel pump that is not supplying sufficient fuel, causing a lean condition, and hence «fooling» the O2 sensors (pre and post) as to the status (i.e., efficiency)...

Oxygen sensors tell the ECU whether the engine is running rich (too much fuel or too little oxygen) or running lean (too much oxygen or too little fuel) as compared to ideal conditions (known as stoichiometric).
