Po 411 code - Cars & Trucks

Do you mean 'P0411'?

What the P0411 code means. P0411 indicates that the ECU has detected the flow from the secondary air injection system to be out-of-specification. This causes the Check Engine Light to be set and displayed on the dashboard.

101,380 and 118. These together is a no start. Take it to a garage. Just a guess, but I would be looking into the wiring. You waited to long to have a problem fixed. One bad part over time will lead to many codes. The PCM is trying to adjust to make the engine run right. Throwing other sensor out of range. Out of range pops a code.

the first code is to do with the secondary air injection optical sensor not reading correctly and i suspect it's that causing the second code which is catalytic convertor reading out of range , so get the optical sensor sorted , may be the ECU or PCM wiring or the sensor itself

Forget to write it down?

Generic or Manufacturer?

There are 41 Generic O2 Codes

PO 131--bank 1 sensor 1
PO 137--bank1 sensor 2
PO 143--bank1 sensor 3
PO 151--bank2 sensor 1
PO 157--bank1 sensor2
PO 163--bank2 sensor 3

CODE PO411 - SECONDARY AIR SYSTEM INCORRECT UPSTREAM FLOW DETECTED. POSSIBLE CAUSES, AIR PUMP OUTPUT IS BLOCKED, AIR BYPASS SOLENOID LEAKING OR BLOCKED, AIR BYPASS SOLENOID IS STUCK OPEN OR STUCK CLOSED. AIR INJECTION PUMP HOSES LEAKING, PCM HAS FAILED.

PO 134 = 02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 1 SENSOR1)
PO 153 =02 SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 1)
PO 154 =02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 2 SENSOR 1)
PO 155= 02 SENSOR HEATER CIRCUIT MALFUNCTION (BANK 2 SENSOR 1)
PO 171= SYSTEM TOO LEAN (BANK 1)
PO 174= SYSTEM TOO LEAN (BANK 2)
I WOULD SAY YOU HAVE FAULTY OXYGEN SENSORS CAUSING THE ENGINE TO RUN TOO LEAN REPLACE THEM AND YOU SHOULD BE BACK IN BUISNESS

hi p -codes are as follows po 301 cylinder 1 missfire detected
po 304 cylinder 4 missfire detected
po 335 crankshaft position sensor A circuit malfunctio
po 750 shift solenoid A malfunction

Code 116- Engine coolant temperature (ECT) sensor out of range, I would replace it.

Code 411- Idle speed system not controlling idle properly (too High)
Code 412- Idle speed system not cotrolling idle properly (too Low)

After replacing the ECT clear codes by disconnecting battery positive for at least ten seconds, see if codes 411, 412 return, if so clean or replace the Idle Air Control solenoid (IAC), repeat clearing of codes. Hope this helps, let me know.

i think that is for the gps cord interface systems reset by disconnecting the power terminalt o the batt. ans wait 3-5 mins. then reconnect. see if it is still on

Check all your vacume lines one may have a crack in it
