Workhorse "Reduced Engine Power"

Any chance it has a chip on it? Do you have an exhaust gas temp sensor? If that exhaust gas gets hot it may drop into limp mode.

Thanks for all the replies. I finally got a chance to take it to an authorized Workhorse repair facility in Penticton, BC and they had it for awhile testing this and that. They didn't seem too knowledgeable about this type of problem but they had a vast network to draw on. The service manager talked to mechanics that he knew that had lots of experience both at GM and Workhorse as far away as Chicago. He finally found a solution with advice from the local race track speedway manager. Told him the symptoms and he immediately suggested the TPS sensor on the transmission. That was removed and cleaned and reattached and the problem went away almost completely. I got home from the trip and went to dump the waste tanks. Put it in reverse and hit the gas and then brake several times to agitate the black water tank and it went into reduced power again. But generally I'm satisfied with the service received by Cullen Diesel in Penticton. And I advised the dealership where I bought the motor home of the situation and they picked up the bill.

Google "reduced engine power". Lots of info out there.

This problem happens when I step on the gas from stand still. I am stopped, put it in reverse and step on the gas pedal. I hear the engine just start to rev up and then it drops out. I tried to take a run up from level and made it part way up the hill but when the grade got to its steepest, it died out again.

Just how far are you going in reverse up this hill? A few feet or a block or two?

Thanks for the positive reply rockhillmanor. I had my regular mechanic put it on his OBD2 reader, and there are no "stored" fault codes.
I think I had the OD switch on atleast some of the time but not sure. When I said local Workhorse repair facility, I meant three hours away. I took it to my regular mechanic who also works on buses and trucks.
@RoyF, thanks for the suggestion. Yes, I read in the manual that the Reduced Eng. Power indicator is a protection thing, but it seems that the RV should have enough power to be able to back up a hill. Thanks.

One reason (there may be others) for Reduced Engine Power is engine protecting itself from overheating. Bad thermostat, bad water pump, low on coolant, slipping belts, ... .

...dash readout said Reduced Eng. Power.
....Authourized repair facility has never heard of this and there are no fault codes in the computer.

How can they tell you there are no fault codes when there is a dash reading for it? OR did you have it tested and there were no fault codes showing a fault? Either way I'd take it to a 'dealer' instead of just an authorized facility.

Is the light on or off in the gear shift lever for OD when you drop it in reverse?

Good Luck

Good luck getting any response from Workhorse. I had a problem with my dash air on my '04 Winnie Sightseer. Workhorse blamed Winnebago and Winnebago blamed Workhorse. It was in the shop more than on the road. I ended up successfully suing Winnebago and getting most of my money back through Lemon Law. Not trying to scare you, but just be prepared for very poor customer service from both companies. Hopefully they've upped their game since 2006 when I was dealing with them.
