2005 ford expedition with 5.4 L engine , transmission 4R75E RWD
service manual data. on errors
p07xx and P17xx are bad tranny dtc coded errors''
p0708- Digital TR sensor circuit TR3A open (TR means transmission range switch)
p1702 is Digital TR circuit reading in between gear position during KOEO/KOER
we have car. spec. now.
p21xx is hard throttle errors.
p2121 is bad TWB, throttle by wire, and limp home mode it lands.
P2121 - Accelerator Pedal Position (APP) Sensor Circuit 1 Range/Performance
P2126 - Accelerator Pedal Position (APP) Sensor Circuit 2 Range/Performance
P2131 - Accelerator Pedal Position (APP) Sensor Circuit 3 Range/Performance
end
so resetting all DTC error via scan tool REST , all come back driving?
even driving around the block, slow ,in limphome mode dupe to TWG failing
no not caused by failsafe = limp mode, limp mode for TWB is to keep car from running over the kids,etc.
with throttle controls OUT OF CONTROL.
keep in mine TBW can fail parked in the drive way in park (PRNDL:) with driver pumping the throttle pedal.
