Disconnect the servo at the receiver, remove the servo horn and linkage from the servo. Remove the four screws that hold the servo to the chassis. Replace with new servo, plug new servo into receiver and turn on transmitter and receiver. With transmitter and receiver on reattach servo horn and linkage. This will make sure that the servo is centered at neutral throttle.

MY PRIDE REVO MOBILITY SCOOTER IS 3 YEARS OLD AND IS STARTING TO HAVE A INTERMITTENT FAULT OF GOING SLOW AND THEN FAST LIKE HAVE DIRTY PETROL IN A CARBURETTER IN A CAR


I know what the problem is as I have had it no less than 3 times with my own Revo. The Throttle Pot needs replacing. Luckily they aren't very expensive and you can fit it yourself if you are a handy sort of person. It just involves turning a screw to take out the old one and put in a new one. You can find diagrams on how to do it on the Internet. If you call a mobility company to come out and do it for you, they usually charge about £50 as a Call Out Fee.

The Revos seem prone to this throttle pot problem. Hope you get it fixed soon.

I have a 07 yamaha r1 and im getting 2 codes 22 and 60 and im not getting a throtle response what can it be?


Fault code No. 22 Symptom >> Air temperature sensor: open or short circuit detected.
Item/components and probable cause
1 Connections Air temperature sensor coupler Main wire harness ECU coupler Check the coupler for any pins that may have pulled out. Check the locking condition of the coupler. If there is a malfunction, repair it and connect the coupler securely. 2 Open or short circuit in wire harness. Repair or replace if there is an open or short circuit. Between air temperature sensor coupler and ECU coupler.(Brown/White)(Black/Blue) 3 Defective air temperature sensor. > Replace if defective.
Code 22 > Reinstated automatically if a normal signal is received.


Fault code No.: 60 Symptom: Throttle servo motor: open or short circuit detected. Defective throttle servo motor. Malfunction in ECU (servo motor driving system). Probable cause of malfunction: •Open or short circuit in wire harness. •Defective throttle servo motor (potentiometer circuit). •Stuck throttle servo motor (mechanism). •Stuck throttle servo motor (motor). •Malfunction in ECU. Diagnostic code No.: 01 FIRST thing to do is CHECK the ETV Fuse - 7.5A I think - This might NOT be in the main fuse box.
Hope this helps

My trx 3.3 idles fine but when you turn the remote on it takes off


you either need to adjust your servo or your idle screw on your controller. when you turn your remote on, it's opening up the throttle causing it to take off. turn on your remote without starting it and if you cant get it to the idle position with the trim screw on the controller, adjust your servo linkage so that it does.

It appears the steering locked up. What do I do?


Make sure that no debris (stones, sticks, etc.) have gotten jammed in tie rods or steering servo. Check to see if servo is trying to move, you should be able to hear it when you turn the wheel on the transmitter. If the servo is not working at all, it could be faulty, came disconnected at the receiver, or receiver pack has too low of voltage. If the servo is trying to turn, check the servo saver to make sure it has not loosened or has been damaged.

E maxx steering is too tight


You may have something too tight on your steering linkages, or you may just want to upgrade to a better servo. My Revo's servos are all metal gear and I have never had a problem with them. Receiver batteries on my truck were weak and the tires were hard to turn as well, so check your batteries
