Lincoln 1996 what does po411 means what the problem

I am thinking you mean rear end auto lift air bags. try trouble shooting through you tube or google auto zone auto trouble shooting site.

P0300 random misfire, p0302 cylinder 2 misfire, p0304 cylinder 4 misfire, p0411 secondary air injection system incorrect flow detected, p1296 cooling system malfunction

How's the motor look around the valve covers,just because the oil light comes on doesn't mean the only problem is low oil,could mean low oil pressure,which is caused by many reasons.

That code means that you have a, secondry air injection system ,incorrect flow detected

Your P2004 code relates to inlet manifold air control actuator or solenoid on bank 1 stuck open, your code PO411 relates to secondary air injection system, (AIR ) incorrect flow detected. Obviuosly both codes are linked to one fault,

P0411 is Secondary Air Injection (AIR) Incorrect Air Flow Detected. Without knowing what year/Model and engine you have it's a guess as to the proper fix.

code po411 secondary air injection system incorrect flow,possible causes , faulty air pump or faulty air pump vacuum valve or faulty check valve.

PO411-Secondary Air Injection System
Incorrect Flow Detected

There are a few components to be checked,
so there is no way to tell you what is wrong

Like all problems you will need professional
help.

The light means you are low on fluid now. If your rear brakes are not working you have a master cylinder or proportioning valve problem. You may also have a leak at the rear.

The P0410 code refers to the emissions system.
The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.

Good luck!!!
