05 Chrysler 300c 5.7 with codes P1416 and P2784- where do I start first? what other things sind I look out for? Any Suggestions? Please Help! Thank you....


its a diesel engine right
is it turbo-ed

very complicated engines with all the electronics
best guess....could be very wrong
suggests cylinder 6 is down on intake pressure
and Input/Turbine speed sensor might be that cause of that


thats the two issues .
.might need a Chrysler service division to sort out

P2784.....generic code only

I replaced my secondary air check valve on my 2001 chevy tahoe but code 1416 still comes up. what else can i check


here is what i found on p1416.



P1416 Chevrolet
P1416 Chevrolet - Secondary Air Injection System Bank 2
Possible causes
- Faulty Secondary Air Injection (AIR) pump
- Secondary Air Injection check valve bank 2
- Secondary Air Injection (AIR) pump electrical circuit fault
- Blocked Secondary Air Injection (AIR) system

When is the code detected?

The P1416 code is set when no O2 sensor voltage change is detected by the Engine Control Module (ECM).


Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)


P1416 Chevrolet Description
An Secondary Air Injection (AIR) pump is used on this vehicle to lower tail pipe emissions on start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump. The Powertrain Control Module (PCM) monitors the HO2S voltages to diagnose the AIR system. During the AIR test the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.

P1416


P1416 Port Air Circuit Malfunction/ (AIR) System Bank 2 bank 2 is the passenger side of the engine, and the AIR system usually has something to do with the exhaust. Look for broken hoses, vacuum lines, leaking gaskets, anything that could cause air to escape. Check your vacuum lines carefully by using a propane UNLIT propane torch and go around every single vacuum line with the engine running. If the engine rpms increases, you have found the leak. If you find nothing amiss, take it to a professional and do not just throw parts at the problem. You will be money ahead.

1416 means that you are running lean while the smog pump is on.
It could also be likely the vacswitch on the smog pump is the causes.
