Hello and Help!

Hi all,
I haven’t even done my introduction yet but a problem popped up already.

I picked up my bus and drove it 1k miles home. All was good.
2001 Thomas Rear Engine
CAT 3126b
Allison 3060
182,344 miles
6C43AAE8-99FF-41B8-AF64-39AA42CC0784-427-000000381E3B2EDF.jpeg

That was a week ago. Yesterday I started her up.
Idles great.
Air came up to pressure
Of course I had to run all over unlocking doors and checking hatches to stop the buzzing.
I hit the Drive button and started moving forward but the gas pedal acted like it wasn’t even connected. I can’t rev the motor in D or N or R for that matter. I can feel the trans shifting. I probably could drive around the block at idle speed. She moves in forward and reverse.

I haven’t worked on it yet. But I may have done something like hit the wrong button somewhere?

Thanks. I will send a pic on the dash from my cell.

Is it throwing any codes?

I would be looking at the throttle pedal and it's wiring/connections to the ECM.

The throttle is electronic.

The symptoms that you are having are very much like what I have seen on two other rigs that turned out to be a failed throttle sensor.

Good luck.

Thanks. I went out and wiggled wires, followed wires, and checked fuses. I couldn’t find anything obvious.

What you say Steve makes perfect sense. I am going to take the TPS off and look at it. Then tomorrow when business are open again, I’ll call around and see how much a new part will cost. Or used? I’ll have plenty of time since we are bugging out for tropical storm Gordon. The bus will be fine where she is.

Thanks again, I’ll let you know what happens.
Dave

Btw. What do I need in order to get codes from the ecu? And do you know where it is located?

Hey Meathead,

I have a Bluebird with a Cummins so your bus may be quite different. Thomas/CAT owners feel free to step in here.....

On mine there is a 9pin connector under the dash for connecting a j1939 code reader. Similar to the OBDII scanners for cars. Next to this connector is a switch. Holding that switch down while turning on the ignition causes codes to flash on a light on the dash. Or you can plug something like the Scanguage into the connector and read them.

I ordered the part. I’m pretty sure that’s it. I guess in the long run I’m going to have to be able to retrieve the ecu codes. I’ll let you know how it goes. Thanks Again!

For anyone else looking at this.
I found out how to get the codes out of my bus and other Thomas bus/engine combinations.

I got the Scangauge Diesel for my short bus. It can read and clear codes but is typically used as a dashboard to show values that aren't made available on your dashboard otherwise. I use mine to show my average trip MPG, turbo pressure, voltage, and water temperature. https://amzn.to/2Qa00Ni
