ECND | I had an '08 do the same thing…..the dealer found a kink in a rubber suction hose (about 4" in length) coming out of the tank. Said it's a common problem. This actually happened on a trip so we stopped into the closest dealer and he had a story that it was the injectors that were wore out and excessive flow, causing too much suction and setting off the sensor to the filter…thinking it is plugged. Anyway it was a 10 minute fix at the local dealer and NO CHARGE. Hope you find your problem. Darren | |
