Throttle Body Test

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If the malfunction indicator lamp (MIL) has been reported on, check for diagnostic trouble codes (DTCs).

Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

Turn the ignition switch to ON (II).
Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
Start the engine. Hold the engine speed at 3, 000 rpm without load (in P or N) until the radiator fan comes on, then let it idle.
Check the REL TP SENSOR in the DATA LIST with the HDS. The reading should be below 2.56 percent. If it is not, clean the throttle body (see THROTTLE BODY CLEANING ).
