DIAGNOSTIC TROUBLE CODE (DTC) – P1320 CRANKSHAFT SEGMENT
PERIOD SEGMENT ADAPTATION AT LIMIT
Circuit Description
The 58X reference signal is produced by the Crankshaft
Position (CKP) sensor. During one crankshaft revolu-
tion, 58 crankshaft pulses will be produced. The Engine
Control Module (ECM) uses the 58X reference signal to
calculate engine rpm and CKP. The ECM constantly
monitors the number of pulses on the 58X reference cir-
cuit and compares them to the number of Camshaft
Position (CMP) signal pulses being received. If the ECM
receives and incorrect number of pulses on the 58X ref-
erence circuit, Diagnostic Trouble Code (DTC) P0320
will set.
Conditions for Setting the DTC

Engine is running.

Number of extra or missing teeth is greater than or
equal to 2 per revolution.

Above condition is detected in 10 of 100 crankshaft
rotations.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.

A history DTC is stored.Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.
Diagnostic Aids
An intermittent may be caused by a poor connection,
rubbed-through wire insulation or a wire broken inside
the insulation. Check for:

Poor connection – Inspect the ECM harness and con-
nectors for improper mating, broken locks, improperly
formed or damaged terminals, and poor terminal-to-
wire connections.

Damaged harness – Inspect the wiring harness for
damage. If the harness appears to be OK, disconnect
the ECM, turn the ignition ON and observe a voltme-
ter connected to the 58X reference circuit at the ECM
harness connector while moving the connectors and
the wiring harnesses related to the ECM. A change in
voltage will indicate the location of the fault.

Reviewing the Failure Records vehicle mileage since
the diagnostic test last failed may help determine how
often the condition that caused the DTC to be set oc-
curs. This may assist in diagnosing the condition.

sor mounted in the high pressure side of the A/C refrig-
erant system to monitor A/C refrigerant pressure. The
engine control module (ECM) uses this information to
turn ON the engine coolant fans when the A/C refriger-
ant pressure is high and to keep the compressor disen-
gaged when A/C refrigerant pressure is excessively high
or low.

2B – 2 WHEEL ALIGNMENT
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
FOUR WHEEL ALIGNMENT
The first responsibility of engineering is to design safe
steering and suspension systems. Each component
must be strong enough to withstand and absorb extreme
punishment. Both the steering system and the front and
the rear suspension must function geometrically with the
body mass.
The steering and the suspension systems require that
the front wheels self-return and that the tire rolling effort
and the road friction be held to a negligible force in order
to allow the customer to direct the vehicle with the least
effort and the most comfort.
A complete wheel alignment check should include mea-
surements of the rear toe and camber.
Four-wheel alignment assures that all four wheels will be
running in precisely the same direction.
When the vehicle is geometrically aligned, fuel economy
and tire life are at their peak, and steering and perfor-
mance are maximized.
TOE
D16A006A
Toe–in is the turning in of the tires, while toe–out is the
turning out of the tires from the geometric centerline or
thrust line. The toe ensures parallel rolling of the wheels.
The toe serves to offset the small deflections of the
wheel support system which occur when the vehicle is
rolling forward. The specified toe angle is the setting
which achieves–degrees (0
) of toe when the vehicle is
moving.
Incorrect toe-in or toe-out will cause tire wear and re-
duced fuel economy. As the individual steering and sus-
pension components wear from vehicle mileage,
additional toe will be needed to compensate for the
wear.
Always correct the toe dimension last.
CASTER
D16A008A
Caster is the tilting of the uppermost point of the steering
axis either forward or backward from the vertical when
viewed from the side of the vehicle. A backward tilt is
positive, and a forward tilt is negative. Caster influences
directional control of the steering but does not affect tire
wear. Weak springs or overloading a vehicle will affect
caster. One wheel with more positive caster will pull to-
ward the center of the car. This condition will cause the
car to move or lean toward the side with the least
amount of positive caster. Caster is measured in de-
grees and is not adjustable.
CAMBER
D16A007A
Camber is the tilting of the top of the tire from the vertical
when viewed from the front of the vehicle. When the
tires tilt outward, the camber is positive. When the tires
tilt inward, the camber is negative. The camber angle is
measured in degrees from the vertical. Camber in-
fluences both directional control and tire wear.
If the vehicle has too much positive camber, the outside
shoulder of the tire will wear. If the vehicle has too much
negative camber, the inside shoulder of the tire will wear.
Camber is measured in degrees and is not adjustable.
