Cautions and notes
NOTE: The only way a DTC P1000 can be removed
from memory is when all the OBDII monitors have successfully completed during normal vehicle operation.
from memory is when all the OBDII monitors have successfully completed during normal vehicle operation.
Test sequence and decision path
1. Were any other DTCs detected with P1000?
If other codes are present, analyse and correct the
other codes first. Complete an OBDII drive cycle
and return to step 2 if the P1000 code is not
cleared.
2. If the P1000 code is not cleared by an OBDII
drive cycle, Check the VSS and ECT signals:
Connect the WDS for a road test and set up to
monitor the VSS signal and the Engine Coolant
Temperature signal at the PCM.
Drive the vehicle long enough to achieve the
highest engine operating temperature. Monitor
the VSS and ECT signals during this road test.
3. If the VSS signal indicated actual road speed, this
was not the cause of the P1000. Go to step 4.
If the VSS signal does not indicate actual road
speed, analyse the VSS problem using the procedure in P0720 analysis.
Run the OBDII drive cycle to clear the P1000
code.
4. Monitor the engine coolant temperature. If the
ECT reading was greater than 180°F (82°C), this is
not the cause of the uncleared P1000. Complete
a full OBDII drive cycle to reset the code.
If the ECT reading does not indicate more than
180°F (82°C) for a fully warmed up engine, analyse the ECT problem using the procedure in
P0117 analysis.
Run the OBDII drive cycle to clear the P1000
code.
