I have a 2000 6 speed with 42000 miles that is stock except for a K and N air filter put on 6 months ago. My problem is an error code pcm-p 0410 that comes on every 30 miles after I reset it. The check engine light comes on and the car runs fine. I'm about ready to take it to the dealer. Any other thoughts? The code is for the air injection system and one mechanic said it may be my "hoover". :smash: :grouphug:

 

It is either the something in the electrical supply line or the air pump itself. The code indicates the air pump is not supplying air to either intake bank.

CIRCUIT DESCRIPTION
An 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 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.

If the PCM determines that the HO2S voltages for both banks did not respond as expected during the tests, DTC P0410 sets. If only one sensor responded, the PCM sets either a DTC P1415 or P1416 to indicate on which bank the AIR system is inoperative.

CONDITIONS FOR RUNNING THE DTC


DTCs P0101, P0102, P0103, P0107, P0108, P0112, P0113, P0117, P0118, P0125, P0171-P0175, P0200, P0300, P0335, P0336, P0351-P0358, P0440, P0442, P0443, P0446, P0449, P1120, P1220, P1221, P1258, P1441 and HO2S DTCs are not set.
Fuel level greater than 12.5 percent but less than 87.5 percent.
The engine is running for greater than 2.0 seconds .
The maximum air flow is 25 g/s
The air fuel ratio is 14.7:1
The engine load is less than 34 percent.
The ignition voltage is greater than 11.7 volts .
Engine is not operating in Power Enrichment, Decel Fuel Shut-off, or Catalyst Over-Temperature modes.
The engine is operating in closed loop for greater than 15 seconds .
The engine speed is greater than 718 RPM .
The ECT is greater than 80°C (176°F) but less than 110°C (230°F) .
The IAT is greater than -2°C (28.4°F) .
The fuel system is operating in fuel trim cells 1, 2, 4, 5, or 6.
CONDITIONS FOR SETTING THE DTC
The HO2S voltage does not go below 222 mV for 1.3 seconds , when the AIR pump turns ON during closed loop operation.
OR
The short term fuel trim does not change more than a predetermined value, when the AIR pump turns ON during closed loop operation.

ACTION TAKEN WHEN THE DTC SETS


The PCM illuminates the Malfunction Indicator Lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and tails.
The PCM records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the PCM stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the PCM records the operating conditions at the time of the failure. The PCM writes the conditions to the Freeze Frame and updates the Failure Records.
CONDITIONS FOR CLEARING THE MIL/DTC


The PCM turns the Malfunction Indicator Lamp (MIL) OFF after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A last test failed (current DTC) clears when the diagnostic runs and does not fail.
A History DTC clears after 40 consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures.
Use a scan tool in order to clear the MIL/DTC.

 

Thanks for all the info. I'm going to bring it in to the dealer in the am. :beatdeadhorse:

 

Richin... is all that from the Shop Manual? If so, I need to change my before bedtime reading! Thanks. :yesnod:

 

I like this better. $15.00 a year and it keeps up on TSBs e.t.c.
