Diagnostic Trouble Code (DTC) 

P1310  ION Sensing Module Diagnosis

060R100135

Circuit Description

The Power Control Module (PCM) checks the validity of
the signals used in the ION Sensing module at the
following engine operating conditions.

D

The Deceleration Fuel Cut Off (DFCO) test is
performed to evaluate the Combustion Quality (CQ)
signal pulse width. If it is below a predetermined value,
the value it is expected to be during DFCO conditions.
If the CQ signal pilse width is above the predetermined
threshold, the fail counter will be incremented. If the
failure counter exceeds the calibration, then the test is
complete and a failure will be reported.

D

The Power Enrichment (PE) test is performed to
evaluate the Combustion Quality (CQ) signal pulse
width. If it is below a predetermined value, the value it
is expected to be during PE conditions.
If the CQ signal pulse width is above the
predetermined  threshold, the fail counter will be
incremented. If the failure counter exceeds the
calibration, then the test is complete and a failure will
be reported.

D

The Combustion Quality (CQ) test is performed to
check if inappropriate (CQ) signal status were
detected. If missing CQ pulses or multiple CQ pulses
or CQ pulse width calculation errors were detected, the
fail counter will be incremented. If the failure counter
exceeds the calibration, then the test is complete and
a failure will be reported.

Conditions for setting the DTC

D

Ignition voltage is between 10volt and 16 volts.

D

MAP sensor signal  is between 26kPa and 100 kPa.

D

Fuel level is more than 19%.

D

Engine speed  is between 650rpm and 6250rpm.

D

No Crank DTCs set.

D

No System voltage DTCs set.

D

CQ pulse width is less than 30

m

s or more than 1070

m

s.

Action Taken When the DTC Sets

D

The PCM will illuminate the malfunction indicator lamp
(MIL) the first time the fault is detected.

D

The PCM calculates an air flow value based on idle air
control valve position, throttle position, RPM and
barometric pressure.

D

The PCM will store conditions which were present
when the DTC was set as Freeze Frame and in the
Failure Records data.

Conditions for Clearing the MIL/DTC

D

The PCM will turn the MIL “OFF” on the third
consecutive trip cycle during which the diagnostic has
been run and the fault condition is no longer present.

D

A history DTC P1310 will clear after 40 consecutive trip
cycle during which the warm up cycles have occurred
without a fault.
