How are the brake lights behaving?
Hadn't noticed your last post...

ECM- 941F
Brake pedal sensor faulty
signal.
(5 cylinder non- turbo)
This DTC is to detect discr
epancies between the brake pedal
sensor and the brake light switch.
If, for more than
0.32 seconds,
the pedal sensor indicates that
the pedal is pressed beyond a
pre determined limit, but the brake light switch is not active, the
fault is set and the DTC ECM-941F is posted in the ECM.
If the DTC is posted the brake
pedal position value and the brake
light switch should be compared
to make sure that the pedal
sensor changes with pedal travel
and that the switch also goes
on and off with pedal travel. If
the switch and sensor behave
correctly, download the latest ETS software.
Downloading the latest ETS soft
ware increases the detection
capability of this monitor. As
before detecting faults for brake
light switch coming on, but now also checking that it goes off
when the position sensor indicates the pedal is released. The
detection time has been increased to 2 seconds and the number
of detections during a driving cycle is now 30. Brake lamp
operation should be verified after repair/software.
