Check for a vacuum leak on the egr valve or intake

Sorry, I never noticed this post, for some reason I did not get an email from Fixya. If it is not too late..........
p0110 is the Intake Air Temp sensor or its wiring connector at fault. This is located at the side of the air cleaner housing.
p0135 is a fault in the No 1 oxygen sensor in bank 1, or its wiring connector. This thing is located in the exhaust manifold under the sheet metal shield at the front of the engine
p0450 is an evaporative emission system pressure sensor fault. Many people recommend replacing the fuel filler cap gasket before going further with this one

p1410 and p1411 indicate an EGR valve malfunction, and it may be enough to simply clean and check it, located on the engine next to the firewall. Also check the vacuum modulator and Vacuum Switch Valve, as shown here p46, 146, 152, 190

P1411 = Secondary air injection system, bank 2 - insufficient flow detected.
Probable cause: Intake leak, hose(s) blocked / leaking, secondary air system valve / solenoid.

P1423 = Secondary air injection system, bank 1 - insufficient flow detected.
Probable cause: Intake leak, hose(s) blocked / leaking, secondary air system valve / solenoid.

check the air hose from the air pump might be leaking

Cylinder #1 reactivation control performance is the code description.

p1423 Secondary Air Injection Bank 1 flow too low

P0431 Warm Up Catalyst, Bank 2 Efficiency Below Threshold/Limit

P1411 Secondary air injection fault, this is related to the P1423.

Code is - Secondary air injection system, bank 2 flow too low.

Check fuse for sec. air injection pump.
Check vacuum hoses
Check piping from pump to sec. air injection valve. (combi. valve)

for P1392 you have to change your Bank 2 CMP sensor
