check engine light question

I was driving around today and the check engine light came on. Is there a way to reset it so I can see if it was a fluke or if there is really something wrong.
Thanks

I had the same thing happen before I put mine into storage this past year. Mine's an '04. I called the Dealer and according to them this sometimes happens and the light will "correct itself." I thought it was BS, but they were actually right. The light came on a few times within a few weeks, then somehow shut off for good.

The Dealer told me as long as the light is not blinking that no damage will be done. So if your light is blinking I would definitely take it in, otherwise you may want to wait it out and see.

Ness,
There are probably 50 different things that will cause the "check engine light" to illuminate. Check to see what code has been set.

Try clearing DTC's on the DIC. That should reset the check engine light. If it doesn't then theres a problem and you may need to take the car into a dealership.

search this forum for the word "code" or codes..

instructions will come up with how to read the codes from your dash.. and what the codes mean..

Never, ever, NEVER believe what some "dealer" tells you. You too need to check for the DTC to see why the light came on. If it hasn't happened again the problem may indeed have "corrected itself" but wouldn't it be nice to know what happened to cause that light to come on?

B2282/B2284 Have to do with the driver door module. Since there is no "C", I wouldn't worry about it.


P1416
CIRCUIT DESCRIPTION
The secondary air injection (AIR) pump system is designed to lower exhaust emission levels after a start up. The AIR pump is timed to remain ON for approximately 1 minute after the engine is started. The powertrain control module (PCM) commands the AIR pump relay ON by supplying a ground to the AIR pump relay control circuit. This - action energizes the AIR pump, forcing fresh air into the exhaust stream. The PCM also commands the AIR vacuum control solenoid ON which applies engine vacuum to the AIR shut-off "Valve. With vacuum applied to the AIR shut-off valve, airflow from the AIR pump flows through the pipes/hoses to the exhaust check valves, then enters into the exhaust stream. The air, oxygen, that is introduced into the exhaust system accelerates catalyst operation. When inactive, the check valves and the shut-off valve prevent air flow in either direction.

The PCM detects a system air flow condition by monitoring the heated oxygen sensors (HO2S) and Short Term Fuel Trim during normal Open Loop AIR system operation. This is called a passive test. If the passive test indicates a pass, the PCM takes no further action. If the passive test fails or is inconclusive, the diagnostic will proceed with an intrusive or active test. The PCM will command the AIR system ON during Closed Loop operation under normal operating conditions. The active test will pass or fail based on the response from the HO2S. A lean HO2S response indicates that the AIR system is functioning normally. An increasing Short Term Fuel Trim value also indicates a normal functioning system. The AIR diagnostic consists of the passive test and the active tests. The AIR diagnostic requires failure of the passive and active tests on 2 consecutive key cycles to illuminate the malfunction indicator lamp (MIL) and stores a DTC. If the PCM detects that the HO2S and Short Term Fuel Trim did not respond as expected on one of the engine banks, DTC P1415 or P1416 sets.

CONDITIONS FOR RUNNING THE DTC

- DTCs P0101, P0102, P0103, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0125, P0131, P0132, P0133, P0134, PODS, P0137, P0138, P0140, P015I, P0154, P0155, P0157, P0158, P0160, P016I, P0171, P0172, P0174, P0175, P0200, P0300, P0335, P0336, P0351, P0352, P0353, P0354, P0355, P0356, P0357, P0358, P0440, P0442, P0443, P0446, P0449, PI 120, PI 133, PI 134, PI 153, PI 154, P1220, P1221, P1258, P1441 are not set.
- The engine is running for more than 30 seconds.
- The mass air flow (MAP) is less than 23 g/s.
- The air/fuel ratio is 14.7:1.
The engine load is less than 40 percent.
- The ignition voltage is more than 11.7 volts.
The engine is not operating in the Power Enrichment, the Decel Fuel Shut-off, or the Catalyst Over-Temperature Modes.
- The engine speed is more than 850 RPM.
- The engine coolant temperature (ECT) is between -10 and +110°C (14-230°F).
- The intake air temperature (IAT) is between -10 and +100°C (14-212°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 decrease to less than 222 mV for 13 seconds.
OR
The short-term fuel trim does not change more than a predetermined value.

ACTION TAKEN WHEN THE DTC SETS

- The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
- 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

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

DIAGNOSTIC AIDS

- For any test that requires probing the PCM or probing a component harness connector, use the J 35616-A connector test adapter kit. Using this kit prevents damage to the harness or component terminals.
- Carbon build-up in the exhaust manifold may restrict the amount of air flow necessary to affect the HO2S voltage. If you suspect this condition, remove the air pipe from the manifold and inspect the passage.

Inspect for the following conditions:
- Excessive exhaust system back pressure
- Moisture, water, or debris ingestion into the AIR pump
- Leaking check valves will leave traces of exhaust carbon in the AIR system.
- A vacuum solenoid leaking vacuum will hold the shut-off valve open an exhaust noise may be heard through the air cleaner fuel trims at idle may be higher than normal a DTC may not set. The vacuum lines at the vacuum solenoid cannot be reversed.
- A check valve that flows in both directions causes heat damage to the AIR system components.

Send a PM to "IT L GO". He has answers to a lot of these
little problems.

I ran the diagnostic and the car had 3 codes, P1416HC, B2282H and B2284H.

I saw the b2282 and 2284 state Battery #1 and #2 DCM- Left and the P1416 says Air system bank 2-B. Can someone enlighten me on what these mean.
Thanks

Should I worry about the P1416 code or clear it and see if it happens again? The car does have an aftermarket filter set-up. Will this code hurt anything?

I would clear it and see if it comes back.

I took it out for a 20 mile drive on both the freeway and town- no code yet. I'm keeping my fingers crossed, but I bet it will be back.
