hello I have a 2006 cat 262c serial # mst01071 So here is the issue I am having. it will drive fine at normal speed but then dies down to a crawl. it happens at all rpms high and low. the engine does not stall or reduce power when this happens. I changed the fluid and put a new OEM filter on, and the problem still occurs.
From memory it will most likely require a throttle position sensor (TPS) recalibration to start with. To carry out that procedure will require Cat ET diagnostic software. Question: Does the panel in the upper RH corner of the cab look like this...?
thanks nige for responding i have read all old posts and you seem very knowledgeable
Bugger. You have the only panel that cannot be used to access diagnostics. Back to ET as the only option I’m afraid.
sorry new to this lingo what is et
