What does it means p2258 code for 2003 Ford Focus , Smog test Failed


P2258 Secondary Air Injection System Control A Circuit High

http://www.motorcraftservice.com/vdi...f/OBDSM505.pdf

Secondary air systems typically utilize an electric air pump as well as one or two electrically controlled check valves to deliver air into the exhaust manifold.

The only vehicle which uses secondary air is the 2.3L PZEV Focus. The Focus uses a system with ported air. This means that airflow is delivered to each individual exhaust port. The secondary air pump is energized soon after start-up while the fuel system is in open loop and icing conditions are not likely. After the O2 sensors warm up, the secondary air pump continues to be energized while the fuel system goes into closed loop fuel. The secondary air system continues to run in closed loop fuel until the air pump is de-energized. The typical time period in which the AIR pump is energized is approximately 12 seconds.

The AIR pump flow check monitors the HO2S signal at idle to determine if secondary air is being delivered into the exhaust system. The air/fuel ratio is commanded open-loop rich, the AIR pump is turned on and the time required for the HO2S signal to go lean is monitored. If the HO2S signal does not go lean within the allowable time limit, a low/no flow malfunction is indicated. (P0411)

The electric air pump draws high current and must be energized through a separate relay. Both the primary and secondary circuits are checked for opens and shorts. First, the output driver within the PCM (primary circuit) is checked for circuit continuity (P0412). This circuit energizes the relay and the vacuum-operated check and control valve(s). Next, a feedback circuit from the secondary side of the relay to the PCM is used to check secondary circuit continuity (P2257, P2258).

Code p0411


P0411 = Secondary Air Injection System (B2) - Incorrect Flow
You should check the Secondary Air Injection System: Air Injection Pump, Air Injection Solenoid Valve, Air Hoses & Connections.

2004 ford focus,code p0411


DTC P0411 - Secondary Air Injection System: Incorrect flow detected

Then check all the vacuum lines against the vacuum map on the VECI label under the hood. It's common for the original plastic lines to get brittle & crack, or they can be melted by an exhaust leak from the crossover tube on V8s, but if you have an I6, it doesn't have that tube.

Check IAC and IAC circuit. Check Secondary Air Injection pump, valve, circuit and hoses for leaks, blockages.

Here can find some diagrams: supermotors.net/registry/media/589993

Hope helps.

could be
electric air pump
hose from air pump leak or blocked
air bypass solenoid blocked or not working

Obd code of p0411 on a 1999 ford mustang 3.8 v-6 what do I check to correct


That's s failure of the secondary air pump. It'll have to be changed. It's an emissions component meant to help with cold start emissions. It won't cause engine running trouble but at inspection time you'll fail for smog. Change it before then and you'll be fine.
