Checking Tps Reading - Polaris 2010 Ranger RZR 800 EFI Manual

ELECTRONIC FUEL INJECTION
Verify TPS Tester Reference Voltage
A 5 volt reference voltage from the TPS Tester harness is
required for the TPS test to be accurate. Refer to the instructions
provided with the TPS Tester (2201519-A) or follow the bullet
point steps below to check reference voltage.
Reference Voltage Test:
• Insert black voltmeter probe into the test port as shown.
• Insert red voltmeter probe into the test port as shown
and verify the voltage reads 4.99-5.01 Vdc. If the
reading is low, replace the 9 volt battery.

Checking TPS Reading

1. Remove the driver and passenger seats along with the rear
service panel.
2. Remove the outlet duct from the PVT cover to access the
throttle body.
3. Loosen the hose clamps that secure the throttle body in the
intake boot and intake adaptor. This will allow you to rotate
the throttle body to access the TPS or allow you to remove
the throttle body to perform this procedure.
4. Assemble the TPS Tester according to the instructions.
Refer to "TPS Tester / Regulator" for proper set-up and
testing. Verify the 9 volt tester battery is new.
5. Disconnect the vehicle chassis harness from the TPS.
NOTE: To allow better access to the TPS harness
connection, remove the exhaust pipe and exhaust
silencer.
6. Plug the TPS Tester harness in the TPS harness.
7. Set your voltmeter to read DC Volts. Insert the red and
black voltmeter probes into the test ports as shown.
8. Move the throttle open and closed slowly while reading the
display. The voltage should increase and decrease
smoothly without any "jumps" when the throttle is applied.
9. If voltage varies with throttle movement, continue on to
Step 10. If the sensor did not function correctly, replace it.
