This is an Idle Air Controll Circuit Fault code.

Take the IAC out of the car, plug it back in, turn the key on DO NOT START THE CAR WITH IT REMOVED.

You should see the IAC Pintle move a bit when you turn the key on.

Also, the needle, and seat inside the throttle body should be clean and not covered in soot. You should also clean the throttle body of any soot coking to maintain the desired Idle speed and functionality.

Check enging is on---OBD code is PO171 & p1443---how do i fixed this problem


The most likely cause of these two codes tripping together is a vacuum leak associated with the canister purge system. This system collects the vented gasoline vapor from the fuel tank and when the engine is running purges the canister into the manifold.

The P0171 is an indication that the engine is running lean and the P1443 is a fault associated with the Purge Control Valve Solenoid trouble code control valve.

Inspect under the hood for a disconnect vacuum line.

The photos are examples of the vacuum circuit connect via hoses. Listen for a vacuum leak when the engine is running. It would be a whistle sound. Also if work has been done recently look in the area that the work was done under the hood.

Your best to use Google & do your research on internet
for your vehicle description & put in OBD2 Code P1443

Forget the 300 that is just random misfires & most likely

Work on the P1443 it will be vehicle specific

1996 Ranger-code P1443-"auxillary emmisions controls" is the decription that I got from Advance Auto Parts diagnostic--What can the problem be?


the Canister Purge Assembly. This assembly connects the intake manifold to the charcoal canister and the assembly is made up of hoses, a valve and a sensor. it is located near the front of the engine compartment on the driver’s side (the canister is right behind the driver’s side headlight). Apparently, if there are any cracks in the hoses, or if the valve or the sensor wears out, this will cause the check engine light to come on, and return the P1443 code.

Codes p0402 and p1443 96 ranger


this means exactly what it says, the emission control valve is faulty and needs replacing.
Basically the valve is in an open position when it should be shut or partially shut.
Replace the valve and this should cure both codes.
