TP sensor 1, TP sensor 2 display on the Tech 2 while
moving connectors and wiring harnesses related to the
sensor.
A change in the display will indicate the location of
the fault. If DTC P1299 cannot be duplicated, the
information included in the Faillure Records data can

be useful in determined vehicle mileage since the
DTC was last set.

If it is determined that the DTC occurs intermittently,
performing the DTC P1299 Diagnostic Chart may
isolate the cause of the fault.

Diagnostic Trouble Code (DTC) 

P1310 ION Sensing Module Diagnosis

D06R200098

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

D

If it is below a predetermined value, the value it is
expected to be during DFCO 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 Power Enrichment (PE) test is performed to
evaluate the Combustion Quality (CQ) signal pulse
width 

D

If it is below a predetermined value, the value 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 6500rpm.

D

No Crank DTCs set.

D

No System voltage DTCs set.

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.

D

DTC P1310 can be cleared using the Tech 2 “Clear
Info” function or by disconnecting the PCM battery
feed.

Diagnostic Aids

An intermittent may be caused by the following:

D

Poor connections.

D

Misrouted harness.

D

Rubbed through wire insulation.

D

Broken wire inside the insulation.

Check for the following conditions:

D

Poor connection at PCM-Inspect harness connectors
for backed out terminals, improper mating, broken
locks, improperly formed or damaged terminals, and
poor terminal to wire connection.

D

Damaged harness-Inspect the wiring harness for
damage. If the harness appears to be OK, observe the
moving connectors and wiring harnesses related to the
sensor.
A change in the display will indicate the location of
the fault. If DTC P1310 cannot be duplicated, the
information included in the Failure Records data can
be useful in determined vehicle mileage since the
DTC was last set.

If it is determined that the DTC occurs intermittently,
performing the DTC P1310 Diagnostic Chart may
isolate the cause of the fault.
