On my 03 i started getting the above codes. I can clear them and generally for a day or two they go away.
The only symptom I think i have is a high idle, 1300 rpm when I first start the car.
Given the myriad of causes/solutions for these codes, does this point to one more likely culprit than the others?

I am pretty sure it is not the fuel tank cap. I poured sea foam in this tank of fuel, which i have done in the past with not adverse effects.

I am planning on cleaning the SAI valve and the the electric switch this weekend, but was wondering if anyone has additional input.

Thanks,

 

Mine was a crack in the pre-formed hose from SAI pump.




Fault Finding Methodology
Malfunctions can be broadly categorised into two different categories: Flow Faults or Leak Faults.
Additionally, they also differ depending if the corresponding P code exists for both cylinder banks simultaneously or
is unique to one bank, for example:
Faults of each of the four basic types should be investigated in a different priority order, starting with the most logically
plausible cause or component.
Fault Finding Flow Charts
The following flow charts show the order of investigation that should be performed depending on the type of fault
present. These should be treated as guidelines to ensure that the most likely and plausible causes are addressed first.
However, the flow charts assume that no clear or obvious reason for failure exists. If the cause of the malfunction is
immediately obvious, then the flow charts should not be followed.
Once a malfunction is identified, it should be rectified as necessary and the system checked as per the instructions
in the following 'Checking Malfunctions' section.
NOTE: It is not necessary to follow the remainder of the flow chart once a potential root cause has been identified.
Flow Fault Finding chart
1 Fault codes P1412, P1414, P1415 or P1417 present
2 Insufficient flow detected
3 Is fault present on both cylinder banks?
If 'NO' proceed to step 4
If 'YES' proceed to step 8
4 Vacuum supply – Check for: blockage and/or vacuum line disconnected from SAI valve
5 SAI Valve – Check for: jam / diaphragm leak or blockage
6 Delivery Hoses to SAI Valve – Check for: blockage / leaks
7 SAI Pipes to Cylinder Head – Check for: blockage / leaks
8 Electrical Issue – Check for: Related P code (relay/fuse/solenoid), rectify as necessary and check connectors
9 Vacuum Supply – Check for: Blocked/leaking vacuum lines or correct solenoid operation (open/closed)
10 Delivery Hoses – Check for: Blocked/leaking hoses
11 SAI Pump – Check for: Correct operation using TestBook/T4 or pump blockage/failure
12 SAI Valves – Check for: Both SAI Valves jammed/blocked/leaking diaphragms
Leak Fault Finding Chart
1 Fault codes P1413 or P1416 present
2 SAI system leak detected
3 Is fault present on both cylinder banks?
If 'NO' proceed to step 4
If 'YES' proceed to step 5
4 SAI Valve – Check for: leakage
5 Vacuum supply – Check for: solenoid stuck open (mechanical failure) or stuck open (electrical failure)
6 SAI Valve – Check for: leakage from one or both valves

 

I appreciate the time to write that. or copy paste.

either way that is what I am doing this weekend.

Ill let you know.

As of now, there are no symptoms.

 

How do I determine which bank, or if both banks have the code?
I did a visual inspection, not a smoke test, and things seemed to be fine, I ended up cleaning the electric switch out. I then went a few days with out a code. It does not sound like the SAI is running excessively.

I do get the following messages from the OBD.
Fuel system status - Closed loop, using O2 sensor for fuel mix

Secondary Air Intake Status - From outside atmosphere or off

Any thoughts, or do I need to smoke test it? No obviously broken or worn vacuum lines.

 

P1415 Secondary air system fault bank 2Drive cycle D:Signal implausible
P1412 same as above bank 1


check the vacuum line connections....broken, clogged nipples

 

Maybe look them up on
http://enginecodemaster.com

Has most of the codes from Rave in it.

 

Mine had the same codes. The issue was in the preformed tubing where it branches off to the plenum. I had to remove some of the loom to find it. It was actually two breaks. Repaired with vacuum hose and cleared codes, and have not returned.

 

do you have a pic of the line you are referring to?
