I've tried to do a search and can't find the instructions on how to get the codes and the reference list of what they are. I have an intermittent one on the 02 Z, i would just like to see what it is.

I have a feeling that going from Sea-level to 5K ft over night might have something to do with it, but I wan to make sure.

So, if you can point me in that general direction, I would appreciate it.

Thanks!

Perfect, thank you! I could not find them doing a search to save my life.

 

Hmm, well I have a P0410 H C ( h- history, correct, and C current?)

Air system. What does that mean to you?

 

Not to sure, others will chime in, I would reset it and see if it comes back. You are correct, H=history and C=current

 

Thanks, I did a search for the code and read about it. The car has headers, so I'm not sure if that affects this or not. I will have to do some more research.

 

Thanks. I wondered if it was something similar to that. I've seen that on other vehicles when I had an EVAP code. I have not put fuel in the car since it arrived, I will check that and go from there.

EDIT: this was a response to another post about it might being the gas cap and is no longer here. hmmm. oh well.

 

Sorry pulled the wrong code.

This post by Forum Member Bell about sums it up

I'd start at the manifold and go backwards. Usually it is the line at the manifild that is weak becasue of all the heat...

Peace

Here is the diagnostic info you need the above list is incrementally better than useless. The bottom part of the diagnostic is a table but it doesn't display as a table on the forum.

DTC P0410
Circuit Description
A secondary air injection (AIR) pump is used on this vehicle in order to lower the tail pipe emissions during start-up. The powertrain control module (PCM) supplies a ground to the AIR pump relay, which energizes the AIR pump.
The PCM monitors the heated oxygen sensor (HO2S) voltages in order 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 monitors the short-term fuel trim values for both banks of the engine. If the AIR system is operating correctly, the HO2S voltages should be low, and the short-term fuel trim should be high.
If the PCM determines that the HO2S voltages for both banks did not respond with the expected results during the tests, DTC P0410 sets. If only 1 sensor responded, the PCM sets either DTC P1415 or DTC P1416. The active DTC indicates which bank has the inoperative AIR system.

Conditions for Running the DTC
o DTCs P0101-P0103, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0125, P0171-P0175, P0200, P0300, P0335, P0336, P0351-P0358, P0440, P0442, P0443, P0446, P0449, P1120, P1220, P1221, P1258, or P1441 are not set.
o The fuel level is more than 12.5 percent but less than 87.5 percent.
o The engine is running for more than 30 seconds.
o The maximum air flow is 22 g/s.
o The air fuel ratio is 13.125:1.
o The engine load is less than 40 percent.
o The ignition voltage is more than 11.7 volts.
o Vehicle speed is more than 15 km/h (25 mph).
o The engine is not operating in any of the following modes:
o Power enrichment
o Decel fuel cut-off mode
o The catalyst over temperature
o The engine is operating in a closed loop for more than 15 seconds.
o The engine speed is more than 850 RPM.
o The engine coolant temperature (ECT) is between than -10°C to +110°C (14°F-230°F).
o The intake air temperature (IAT) is between -10°C to +100°C (14°F-212°F).
o The fuel system is operating in fuel trim cells 1, 2, 4, 5, or 6.

Conditions for Setting the DTC
If the AIR pump turns ON during a closed loop operation and the HO2S voltage does not fall below 222 mV for 1.3 seconds.
Or
If the AIR pump turns ON during a closed loop operation and the short-term fuel trim does not change more than a predetermined amount.

Action Taken When the DTC Sets
o The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
o The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

Conditions for Clearing the MIL/DTC
o The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
o A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
o A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
o Clear the MIL and the DTC with a scan tool.

Diagnostic Aids
Important
o Before you service the PCM or the throttle actuator control (TAC), remove any debris from the module connector surfaces, and from the module connector gaskets. Verify that the gaskets are correctly installed. The gaskets prevent debris from contaminating the modules.
o For any test that requires probing the PCM or probing a component harness connector, use the Connector Test Adapter Kit J 35616-A . Using this kit prevents damage to the component terminals and to the harness. Refer to Using Connector Test Adapters in Wiring Systems.
AIR Pump Relay Underhood Electrical Center Terminal Identification
Front of Vehicle
Left Side of Vehicle Ignition B+ Right Side of Vehicle
Pump Supply Control
o For an intermittent condition, refer to Intermittent Conditions .
o An intermittent may be caused by any of the following conditions:
o Low system air flow may cause this DTC to set.
o Excessive exhaust system back pressure
o Moisture, water or debris ingested into the AIR pump
o Pinched, kinked, heat damaged, or deteriorated hoses or vacuum lines
o Restrictions in the pump inlet, duct, or filter
o An AIR pump that has become inoperative and shows signs of exhaust gases in the outlet port would indicate a check valve failure.
o Thoroughly check any circuitry that is suspected of causing the intermittent complaint. Refer to Testing for Intermittent and Poor Connections .
o If a repair is necessary, refer to Wiring Repairs or Connector Repairs .

Test Description
The numbers below refer to the step numbers on the diagnostic table.
3. If DTCs P0412 or P0418 are set, diagnose those DTCs first.
4. Inspects for excess resistance in all of the circuits that are associated with the AIR system.

6. This step tests for power to the AIR pump.
7. This step tests the ground circuit for the AIR pump.
12. This step tests for a grounded circuit between the AIR pump and the AIR pump relay.
22. A restriction in a hose or in a pipe, between the shut-off valve and the point where the system branches to each bank, causes the setting of this DTC . Inspect for kinks or for blockages from the AIR pump to the connection point where the AIR system divides.

Thanks for the help guys. I will have to start digging into this. I assume this will not have any negative effects at this time to the engine, etc?

 

Sure is not useless to me since it gives an individual where to start as opposed to guessing. OP was wanting a reference list of codes and that is what I posted.

Great post on how to fix it.

 

Drove back from club meeting last night and had no cruise control. No codes displayed so I found this post and my service manual. Checked fuse and then manual stated if low voltage, will not work. I cleared codes and works great! Thanks for the info. Was really worried about taking it to a dealer and the mess after.
