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.

DIAGNOSTIC TROUBLE CODE (DTC) – P0327 KNOCK SENSOR CIRCUIT FAULT
Circuit Description
The knock sensor(KS) system is used to detect engine
detonation, allowing the engine control module(ECM) to
retard ignition control spark timing based on the KS sig-
nal being received. The KS produces an AC signal so
that under a no knock condition the signal on the KS cir-
cuit measures about 0.007V AC. The KS signal’s ampli-
tude and frequency depend upon the amount of knock
being experienced. The ECM contains a non-replace-
able knock filter module called a signal-to-noise en-
hancement filter (SNEF) module. This filter module in
the ECM determines whether knock is occurring by
comparing the signal level on the KS circuit with the volt-
age level on the noise channel. The noise channel al-
lows the ECM to reject any false knock signal by
knowing the amount of normal engine mechanical noise
present. Normal engine noise varies depending on en-
gine speed and load. When the ECM determines that an
abnormally low noise channel voltage level is being ex-
perienced, a DTC P0327 will set.
Conditions for Setting the DTC

Knock sensor SPI bus in failure during 7 seconds.

The knock sensor voltage is below 0.2V.

Engine Coolant Temperature is higher than 80°C
(176°F).

Engine rpm is more than 2,500rpm.

DIAGNOSTIC AIDS

complaint should be thoroughly checked for the follow-
ing conditions :

Backed-out terminals.

Improper mating.

Broken locks.

Improperly formed.

Damaged terminals.

Poor terminal-to-wire connections.

Physical damage to the wiring harness.
