I service my 2000 accord SE regularly, one month ago had the 90,000 mile service. I backed my car into the garage and when I closed the garage door it came down on the hood taking my "H" off, a day or two later the SRS light went on the dash board and has been on ever since (about 3 weeks)
Today I went out and started my car. The engine malfunction light is on the dash board, I filled up 4 days ago, however I unscrewed the gas cap and tighted it.
Started the car and the malfunction light was still on.'
I read the manual and it said if that fix worked it would take 3 trips to shut off.
Advice? And is it safe to drive, I work 20 miles from my home and drive in on a highway between 70-80 mph
Do you

For the SRS light. You may shaken the airbag sensor inside the bumper when the garage door hit the hood. You need a visit to the dealership for that.

As for the check engine light, you may want to bring your vehicle to your local Autozone so they can scan the computer. I have no advise for you until I know the code numbers.

The Diagnostic codes from Autozone were P1166 and P1167. If it is the oxygen sensor, how do they know which one it is? Or do they just replace both?

It may not be the sensor. It indicates the heater circuit, which is electrical problem, not the sensor. This is the upstream sensor (Sensor 1) , the one on the exhaust manifold.

DTC P1166: A/F SENSOR (SENSOR 1) HEATER CIRCUIT MALFUNCTION
1.Reset the ECM/PCM (***Don't worry about this***).
2.Start the engine.
Is DTC P1166 indicated?
YES - Go to step 3.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at C102 (located under the under-hood fuse/relay box), the A/F Sensor relay, the A/F Sensor (Sensor 1) and the ECM/PCM. ***Still, you want to check the connection***
3.Check the following fuses:
POWER SEAT (20A) fuse in the under-hood fuse/relay box.
No. 4 ECU (ECM/PCM) CRUISE CONTROL (15A) fuse in the driver's under-dash fuse/relay box.
No. 6 LAF HEATER (20A) in the passenger's under-dash fuse/relay box.
4.Measure voltage between ECM/PCM connector terminals B19 and B20, 30 seconds after the ignition switch is turned ON (II).

Is there battery voltage?
YES - Substitute a known-good ECM/PCM and recheck. If the symptom/indication goes away, replace the original ECM/PCM. NO - Go to step 5
5.Measure voltage between ECM/PCM connector terminals C13 and B20.

6.Turn the ignition switch OFF.
7.Disconnect ECM/PCM connector B (25P).
8.Turn the ignition switch ON (II).
9.Connect ECM/PCM connector terminal B16 to body ground with a jumper wire, then measure voltage between ECM/PCM connector terminals B19 and B20.

Is there battery voltage?
YES - Substitute a known-good ECM/PCM and recheck. If the symptom/indication goes away, replace the original ECM/PCM. NO - Repair open or short in the wire between A/F Sensor (Sensor 1) and ECM/PCM (B19).
10.Turn the ignition switch OFF.
11.Disconnect ECM/PCM connector B (25P) and the A/F Sensor (Sensor 1) 4P connector.
12.Check for continuity between A/F Sensor (Sensor 1) 4P connector terminal No. 3 and body ground.

Is there continuity?
YES - Repair short in the wire between the A/F Sensor (Sensor 1) and ECM/PCM (B19). NO - Go to step 13.
13.Turn the ignition switch ON (II).
14.Measure voltage between ECM/PCM connector terminals B16 and B20


http://www.2carpros.com/forum/automotive_pictures/55316_00accordp1166_5_1.jpg


Is there battery voltage?
YES - Repair open in the wire between the ECM/PCM (C13) and the A/F Sensor (Sensor 1) or Secondary HO2S (Sensor 2). NO - Go to step 15.
15.Check for continuity in the wires between A/F Sensor and the fuses.
Is there continuity?
YES - The wires are OK. Replace the A/F Sensor relay. NO - Repair open in the wire between the A/F Sensor relay and the fuses.

I'll email you the diagnostic for P01167.
