CAT 350 no Throttle response

[weaverworks]

Have experience a throttle problem on my 350 Cat on a Freightliner Chassie, 2005 Tiffin Phaeton. When starting for the first time of the day, if I push down the throttle I get no engine response. This has been going on for about a month. If I let it warm up for 15-20 minutes, it eventually would be okay. Yesterday, nothing helped...no engine response, even after warming up. I had to be towed to Freightliner of San Antonio and am waiting to get in the shop for a diagnosis. Any ideas?

Thanks

Cat does have some sensors that cut off the throttle to prevent engine damage under certain conditions, it could be one of those problems or the sensor.

It was the throttle sending sensor! Attaches to the gas peddle. This has been causing problems off and on for about a month. The technician at Freightliner of San Antonio diagnosed the problem immediately using the computer diagnostic port.
