Throttle Position Sensor, TPS
Checking and Adjustment by the Manual
Please note that I have not performed this check and adjustment as of June 2001. This is just the basic info from the shop manual. If you are a FZ1 owner who performs this operation and would like to contribute first hand information/directions/corrections please post to me for uploading to this page. email@example.com
Checking the Throttle Position Sensor, TPS
….Disconnect the TPS electrical coupler.
….Remove the TPS from the right side carb. Two screw hold it on.
….Connect a pocket tester (set for ohms x 1k) to the TPS. The testers positive lead is connected to the black/blue TPS lead and the testers negative lead to the blue wire of the TPS.
….Check the TPS maximum
resistance, which should be 4-6 k ohms at 68 degrees F (20C). If the TPS is
out of specification replace the unit.
….If the resistance checks out to be in the acceptable range of 4-6 k ohms, re-install the TPS onto the carb.
….Now once again connect
the pocket tester (set at ohms x 1k) to the TPS. This time the testers
positive lead is connected to the yellow wire, and the testers
negative lead to the blue wire.
….While slowly opening the throttle, check that the TPS resistance is within the specified range of 0.4-5.4 k ohms at 68 degrees F (20C) If it is out of spec, replace the TPS.
….If the TPS meets specs, follow the procedure for adjustment before tightening the mounting screws.
Adjusting the Throttle Position Sensor angle, TPS
….The TPS is located on the right side of the bike, on the outside of the outermost carb and is held in position by two screws that can be loosened for adjustment.
….Properly adjust the idle speed first.
….Turn the main switch to
the "ON" position.
….Disconnect the TPS coupler. Lift the tank to get at the coupler.
….Then reconnect the TPS coupler. This will switch the tachometer into the TPS adjustment mode.
….Loosen the two TPS screws.
reading TPS angle: 0 rpm = angle too
small, 5,000 rpm = correct angle, 10,000
= rpm angle too large
….Adjust the TPS angle according to the following information. Note that the angle of the TPS is indicated by the RPM readings which are displayed on the tachometer.
….After adjusting the TPS to the correct angle tighten the TPS screws.
….Then exit the TPS adjustment mode by turning the main switch to off or starting the engine.
