Scan Test is Incomplete P1000 Repair
The computer system
or PCM (powertrain control module) that controls your car is equipped with a basic
operating program. This operating program is designed to control your
engine,
transmission,
emissions, safety systems
and more. If a scan has been performed by using a
code
scanner and a "scan could not be completed" code is retrieved further
troubleshooting is necessary. Usually
a trouble code P1000 or manufacturers equivalent. We have listed several reasons
for this condition.
Step 1 - Stuck Engine Thermostat - If the
engine thermostat
has stuck open it forces the engine coolant to stay at too low of a temperature
causing the computer to stay in open loop. This open loop creates a state of pre-programmed
parameters were no diagnostic tests can be preformed. The computer is constantly
waiting for the engine to heat up to operating temperature for closed loop operation.
Step 2 - Shorted Sensors - The computer relies on information
from the oxygen,
mass air flow,
throttle position,
crankshaft position
and coolant sensors
to operated, if one of these sensors is severely shorted it can cause the computer
to stay in open loop, causing a code gathering incomplete
trouble code.
Step 3 - Shorted Fuel Injector - If a
fuel injector short circuits
it can cause the engine not to run by shorting the injector driver. If the car doesn't
run and a code gathering incomplete trouble code like P1000 is present, it could
be a fuel injector shorted. Unplug all injectors and rescan the system.
