Diagnostic Trouble Code (DTC) P0700

Transaxle Control Module Malfunction

Circuit Description

The Transmission Control Module (TCM) and the Engine Control Module (ECM) are connected through the serial data link circuit. The TCM sends a Class-II P-code status message to the ECM every 100 milliseconds to confirm the transmission is functioning correctly.

If the TCM detects either an A- or B-type malfunction within the transmission, the TCM will send to the ECM a P-code status message to turn the Malfunction Indicator Lamp (MIL) ON and set DTC P0700.

Conditions for Setting the DTC

Received message from the TCM indicating malfunction is detected in TCM.

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/or Failure Records buffers.
A history DTC is stored.

Conditions for Clearing the MIL/DTC

A history DTC will clear after 40 consecutive warm-up cycles without a fault.
DTC(s) can be cleared by using the scan tool.
Disconnecting the ECM battery feed for more than 10 seconds.

Diagnostic Aids

An intermittent may be caused by a poor connection, rubbed-through wire insulation or a wire broken inside the insulation.

Check for a poor connection or damaged ECM/TCM harness. Inspect the serial data link circuit for the following conditions:

Improper mating
Broken locks
Improperly formed
Damaged terminals
Poor terminal-to-wiring connections
Damaged harness

Diagnostic Trouble Code (DTC) P1106

Manifold Absolute Pressure Intermittent High Voltage

Circuit Description

The Manifold Absolute Pressure (MAP) sensor responds to changes in intake manifold pressure (vacuum). The MAP signal voltage to the Engine Control Module (ECM) varies from below 2 volts at idle (high vacuum) to above 4 volts with the key in the ON position, engine not running or at Wide Open Throttle (WOT) (low vacuum).

A "speed density" method of determining engine load is used. This is calculated using inputs from the MAP sensor, the rpm (58X), and the Intake Air Temperature (IAT) sensor. The MAP sensor is the main sensor used in this calculation, and measuring engine load is its main function.

The MAP sensor is also used to determine manifold pressure changes while the linear Exhaust Gas Recirculation (EGR) flow test diagnostic is being run (refer to DTC P0401). This determines the engine vacuum level for some other diagnostics and determines Barometric Pressure (BARO). The ECM compares the MAP sensor signal to calculated MAP based on Throttle Position (TP) and various other engine load factors. If the ECM detects a MAP signal voltage that is intermittently above the calculated value, DTC P1106 will set.

Conditions for Setting the DTC

The MAP is greater than 103 kPa (15 psi).
No TP sensor fail conditions present.
Engine running more than 10 seconds
TP sensor is less than 20 % if rpm is less than 3000.
TP sensor less than 30% if rpm is greater than 3000.

Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will not illuminate.
The ECM will store conditions which were present when the DTC was set as Failure Records data only.
This information will not be stored in the Freeze Frame data.

Conditions for Clearing the MIL/DTC

A history DTC will clear after 40 consecutive warm-up cycles without a fault.
DTC(s) can be cleared by using the scan tool.
Disconnecting the ECM battery feed for more than 10 seconds.

Diagnostic Aids

Check for the following conditions:

Leaking or plugged vacuum supply line to the MAP sensor.
Inspect ECM harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal-towire connection.
Inspect the wiring harness for damage. If the harness appears to be OK, observe the MAP display on the scan tool while moving connectors and wiring harnesses related to the sensor. A change in the display will indicate the location of the fault.

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

Diagnostic Trouble Code (DTC) P1111

Intake Air Temperature Intermittent High Voltage

Circuit Description

The Intake Air Temperature (IAT) sensor is a thermistor which measures the temperature of the air entering the engine. The Engine Control Module (ECM) applies 5 volts through a pull-up resistor to the IAT sensor. When the intake air is cold, the resistance is high, and the ECM will monitor a high signal voltage on the IAT signal circuit. If the intake air is warm, the sensor resistance is lower causing the ECM to monitor a lower voltage. Diagnostic Trouble Code (DTC) P1111 will set when the ECM detects an intermittent high signal voltage in the intake air temperature sensor signal circuit or sensor.

Conditions for Setting the DTC

IAT is less than -42 °C (-44 °F) (SOHC).
IAT is less than -38 °C (-36 °F) (DOHC).

Engine Coolant Temperature (ECT) is above 70 °C (158 °F).

Action Taken When the DTC Sets

The ECM will substitute a default value for IAT.
The ECM will store conditions which were present when the DTC set as Failure Records data only. This information will not be stored as Freeze Frame data.
The Malfunction Indicator Lamp (MIL) will not illuminate.
A history DTC is stored.

Conditions for Clearing the MIL/DTC

A history DTC will clear after 40 consecutive warm-up cycles without a fault.
DTC(s) can be cleared by using the scan tool.
Disconnecting the ECM battery feed for more than 10 seconds.

Diagnostic Aids

Check for the following conditions:

Poor connection at the ECM. Inspect harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal-to-wire connection.
Damaged harness. Inspect the wiring harness for damage. If the harness appears to be OK, observe the IAT display on the scan tool while moving connectors and wiring harnesses related to the IAT sensor. A change in the IAT display will indicate the location of the fault.
Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.

Engine Coolant Temperature Intermittent Low Voltage

Circuit Description

The Engine Coolant Temperature sensor (ECT) is a thermistor mounted in the engine coolant stream. The Engine control Module (ECM) applies 5 volt reference voltage through a pull-up resistor to the ECT signal circuit.

As the engine coolant warms, the sensor resistance is less, and the ECT signal voltage measured at the ECM drops. With a fully warmed engine, the ECT signal voltage should measure about 1.5 to 2.0 volts. If the ECM detects an ECT signal that is intermittently below the range of the ECT sensor, Diagnostic Trouble Code (DTC) P1114 will set.

Conditions for Setting the DTC

ECT is greater than 208.8 °C (407.8 °F) (SOHC).
ECT is greater than 149 °C (300 °F) (DOHC).
Engine has been running for over 60 seconds.

Conditions for Clearing the MIL/DTC

A history DTC will clear after 40 consecutive warm-up cycles without a fault.
DTC(s) can be cleared by using the scan tool.
