Fault remedy
– -G648- Check.
⇒ P age 444
– Pull off temperature
sensor, and measure
reference volt-
age (3.3 V) on signal
line, measured value
block => connect sig-
nal line to earth, if
sensor raw voltage in
measured value block
= 0 V => sensor de-
fective => sensor raw
voltage in measured
value block ap-
prox.=0 V => check
sensor wire to ECU
– Wire to ECU OK, ECU
defective
– -G648- Check.
⇒ P age 444
– Comparison of all
temperatures with
completely cooled
down engine and ter-
minal 15 ON / engine
OFF. Electr. test of
sensor wires;
– -G648- Check.
⇒ P age 444
– Pull off temperature
sensor => sensor raw
voltage in measured
value block "Exh_uR-
awTPFltDs" approx.
reference voltage
(3.3 V) => sensor de-
fective, sensor raw
voltage in measured
value block approx.
0 V => check wire to
ECU
– Wire to ECU OK, ECU
defective
