Throttle Body TestWith using a scan tool/Honda PGM Tester:
- Do not adjust the throttle stop screw. It is preset at the factory.
- If the Malfunction Indicator Lamp (MIL) has been reported on, check for Diagnostic Trouble Codes (DLC).
|1.||With the engine off, check the throttle cable operation. The cable should operate without binding or sticking.|
|2.||Operate the throttle lever by hand to see if the throttle valve and/or shaft are too loose or too tight.|
|3.||Connect the scan tool/Honda PGM Tester to the Data Link Connector (DLC).|
|4.||Turn the ignition switch ON (II).|
|5.||Check the throttle position with the scan tool. There should be about 10% when the throttle is fully closed and about 90% when the throttle is fully opened.|
