D

DTC P1310 can be cleared using the Tech 2 “Clear
Info” function.

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.

Diagnostic Trouble Code (DTC) 

P1311  ION Sensing Module SEC Line 1 Circuit Fault

060R100135

Circuit Description

D

The Power Control Module (PCM) will compare the
secondary current reading to predetermined maximum
and minimum thresholds.
If the secondary current signal pulse width is out of
the predetermined range, the fail counter will be
incremented. If the failure counter exceeds the
calibration, then the PCM is complete and a failure
will be reported. If the sample counter threshold is
reached before the failure threshold, then the PCM is
complete and pass will be reported.

This PCM will detect an open/short circuit in the
secondary current sense input circuit, misfire on the
entire bank for the secondary current sense input
circuit, coil failure, and same internal Ignition Current
Sense System (ICSS) module faults.

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

ION Sensing Module circuit is open or shorted signals
on the SEC 1 line.

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 P1311 will clear after 40 consecutive trip
cycle during which the warm up cycles have occurred
without a fault.

D

DTC P1311 can be cleared using the Tech 2 “Clear
Info” function.

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.

D

A change in the display will indicate the location of the
fault. If DTC P1311 cannot be duplicated, the
information included in the Failure Records data can be
useful in determining vehicle mileage since the DTC
was last set.

D

If it is determined that the DTC occurs intermittently,
performing the DTC P1311 Diagnostic Chart may
isolate the cause of the fault.
