Trimline treadmill T340. what is error code 905? symptom: it runs for fine for a minute, then cuts off, and console starts beeping and flashing. i just replaced speed sensor

It sounds like there may be a mechanical issue with your Trimline T340 treadmill. Here are a few potential causes and solutions to the problem you're experiencing:

1. Belt tension: If the belt is too tight or too loose, it may cause the jolting or skipping you're experiencing. Try adjusting the belt tension following the manufacturer's instructions.
2. Belt alignment: If the belt is not properly aligned, it may cause it to slip or jolt. Check that the belt is centered and properly aligned.
3. Motor issues: If the motor is struggling to keep up with the weight on the treadmill, it may cause the jolting or skipping. Check the motor and make sure it's in good condition. If you're unsure, it may be best to have a professional take a look.
4. Deck and rollers: Check the deck and rollers for wear and damage. If they are worn or damaged, they may be causing the jolting or skipping. Replace any damaged components.
5. Lubrication: Check the treadmill's lubrication. If it's not properly lubricated, it may cause the belt to stick or slip. Follow the manufacturer's instructions for lubrication.

If you're unsure about any of these potential issues or how to resolve them, it may be best to have a professional take a look. Using a treadmill that's not working properly can be dangerous, so it's important to get it fixed as soon as possible.

This has something to do with your controller. It could be the wiring in between the controller and the outlet or it's the controller itself. If it is the controller you probably won't be able to get the part. If you can find one it'll be about $400 and you'll have to replace the belt as for for another $200. If it's a simple wiring issue it's pretty cheap but you definitely need a skilled technician on site.

Ok. So the first thing to try is to calibrate the speed.
You do this by doing the following:

• With the SAFETY KEY in place, hold the ELEVATION UP and SPEED DOWN buttons for five seconds. The console will beep twice, "ENG0" will appear in the Distance window, and a number will appear in the Elevation window.
• Press SELECT until "ENG3" appears; this is for Auto-Calibration.
• Press START to Auto-Calibrate.
• The treadmill will calibrate minimum and maximum speed, and minimum and maximum elevation. When Auto-Calibration is complete, the treadmill will reset to User's start screen. This process takes three to five minutes.

Make sure there are no errors. . .and that the speed goes from super slow to super fast and then stops. . .. if it stays slow. . or stays fast. .or error code appears during calibration, there is a problem.
If after a good calibration sequence, if it still does the stopping and E-1 after 10 seconds. ., then you need to (Power off and disconnect treadmill). . .then unplug the speed sensor from the lower power board, blow into the connector on the wire, and add a little contact cleaner spray to the connector on the board.
Recap: If it actually runs. . .but stops after a few seconds. . but the calibration runs and passes fine. .. .more than likely it is a speed sensor misread or a faulty speed sensor.

However try to LUBE with WD-40 first, if do not work go to

Wondering if there was a solution to the original post? I have one of these and it is doing the exact same thing???

I would recommend throwing it into a large trash can. Trimline parts are very difficult to find and very expensive. What you would have to spend to bring this machine up to useable shape and guarantee another 4 years would be as much as buying a brand new machine of the same quality.
