DIAGNOSIS
*1. Connect the Honda Diagnostic System (HDS) with version 1.012.023 or later software to the 16P data link connector (DLC).*
2. Turn the ignition switch to ON (II). Turn on the HDS.
3. At the screen prompts, enter the VIN and the odometer reading, and then verify the correct date and time.
4. From the System Selection Menu screen, select PGM FI.
5. From the Mode Menu screen, select DTCs/Freeze Data.
6. Enter the repair order number when prompted, then read the screen.
Is DTC P0107 or P0108 set?
Yes - Go to step 7.
No - Go to step 8.
7. Press the freeze data (camera film strip) icon on the right side of the screen. Look at the IAT SENSOR value.
Is the IAT value at or below 32°F (0°) (4.0 volts)? Yes - Press the red DTC icon on the right side of the screen to clear the DTC. Turn the ignition switch to LOCK (0), and then turn off and disconnect the HDS. Go to the appropriate *REPAIR PROCEDURE.*
* No - Continue with normal troubleshooting.*
8. Find out from your customer the approximate ambient air temperature when the problem happened.
Was the ambient air temperature at or below 32°F
(0°C) when the problem happened?
Yes - Go to the appropriate REPAIR
* PROCEDURE.*
* No - Continue with normal troubleshooting.*
*REPAIR PROCEDURE - ACCORD V6, ODYSSEY*
NOTE:
Discard the instructions that came with the kit they are incorrect for this repair. Follow this procedure instead.
1. Unplug the 3P connector from the MAP sensor.
2. Use a small, flat-tip screwdriver to pry out the retainer from the connector. Also, pry out the retainer from the new 3P connector.
3. Remove the No. 1 terminal (YEL/RED wire) from the old 3P connector.
4. Insert the No. 1 terminal (YEL/RED wire) into the left (No. 1) cavity of the new 3P connector.
5. Repeat steps 3 and 4 to transfer the No. 2 terminal (GRN/WHT wire) to the center (No. 2) cavity of the new 3P connector. Repeat steps 3 and 4 to transfer the No. 3 terminal (RED/GRN wire) to the right (No. 3) cavity of the new 3P connector. Discard the old 3P connector.
6. Snap the retainer into place on the new 3P connector.
*7. Accord V6 only: Remove and discard the throttle body cover.*
8. Remove the MAP sensor and the 0-ring from the throttle body (two washer-screws). Discard the sensor and the 0-ring, but save the washer-screws.
* NOTE:
For 1998-99 Accord V6 models, discard the sensor spacer from the kit, and use P/N 16442-P8F-A21, H/C 6562896, instead. Also, discard the adapter harness bracket from the kit. This bracket cannot be mounted to the spacer on those models.*
9. Position the new 0-ring on the throttle body. Then install the sensor spacer with the washer-screws you saved in step 8.
*10. Odyssey, 2000-02 Accord V6 only: Install the adapter harness bracket on the sensor spacer (one flange bolt).*
11. Install the new MAP sensor on the sensor spacer (one washer-screw).
12. Plug the large (gray) end of the adapter harness into the engine harness 3P connector. Then plug the small (black) end of the adapter harness into the MAP sensor.
*13. Odyssey, 2000-02 Accord V6 only: Slide the engine harness 3P connector onto the harness bracket until it clicks into place.*
*14. 1998-99 Accord V6 only: Use a wire tie to secure the engine harness 3P connector to any nearby vacuum hose. Make sure the connector and the harness do not interfere with the throttle cables and the wire tie does not pinch the vacuum hose.*
