Circuit/System Testing

Caution: Use the connector test adapter kit J 35616-A for any test that requires probing the following items:

* The control module harness connectors

* The electrical center fuse/relay cavities

* The component terminals

* The component harness connector

Using this kit will prevent damage caused by the improper probing of connector terminals.

Note: Refer to Diagnostic Aids before performing the Circuit/System Testing.

1. Ignition OFF, disconnect harness connector X2 at the K20 ECM.

2. Connect a test lamp between terminal X2-45 and ground.

Note:

* A DMM connected between the test lamp probe and ground will measure 5-6 V if the test lamp illuminates with low intensity. The

voltage will measure near B+ if the test lamp illuminates with bright intensity.

internal resistance.

- Intake Camshaft Position (CMP) Actuator Park Position Bank 2

DTC P1014

- Exhaust Camshaft Position (CMP) Actuator Park Position Bank 2

Circuit/System Description

The camshaft position (CMP) actuator system enables the engine control module (ECM) to change the camshaft timing of all 4 camshafts while the

engine is operating. The CMP actuator assembly varies the camshaft position in response to directional changes in oil pressure. The CMP actuator

solenoid controls the oil pressure that is applied to advance or retard a camshaft.

The CMP actuator assemblies have an outer housing that is driven by the engine timing chain. Inside the CMP assembly is a wheel with fixed vanes

that is attached to the camshafts. The CMP actuator assemblies are also equipped with a locking pin. The locking pin prevents movement between

the outer housing and the wheel vane assembly on engine start-ups. The CMP actuator is locked until sufficient oil pressure is available to control

the CMP actuator. The locking pin is released by oil pressure before any movement in the CMP actuator assembly takes place.

Circuit/System Description

The engine control module (ECM) uses the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor pulses to monitor the

correlation between the crankshaft and the camshaft position. An improper relative position can be caused by either engine timing or improper

indexing of the camshaft drive chain.

Diagnostic Fault Information

Circuit/System Description

When the ignition switch is placed in the START position, a discrete signal is supplied to the body control module (BCM) notifying it that the

ignition is in the START position. The BCM then sends a message to the engine control module (ECM) that crank has been requested. The ECM

then verifies that the clutch pedal is depressed or the transmission is in Park/Neutral. If it is, the ECM then supplies 12 V to the control circuit of the

starter relay. When this occurs, battery voltage is supplied through the switch of the starter relay to the starter solenoid.

Conditions for Running the DTC

* The ignition is in the START position.

* The system voltage is between 9.5-18 V.

1. Ignition OFF, disconnect the harness connector at the B34 engine coolant temperature (ECT) sensor.

Note: A thermometer can be used to test the sensor off the vehicle.

2. Test the ECT sensor by varying the sensor temperature while monitoring the sensor resistance. Compare the readings with the Temperature

Versus Resistance - Engine Coolant Temperature Sensor (See: Powertrain Management/Computers and Control

Systems/Specifications/Temperature Versus Resistance - Engine Coolant Temperature Sensor) table and verify that the resistance is within 5

% of the specification.

瀚慖f not within the specified range, replace the B34 ECT sensor.

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

Note: You must perform the Circuit/System Verification first.

1. Ignition OFF, remove the Q8 control solenoid valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly

Replacement (See: Powertrain Management/Transmission Control Systems/Actuators and Solenoids - Transmission and

Drivetrain/Actuators and Solenoids - A/T/Shift Solenoid/Service and Repair).

2. Connect the DT-47825-10 - jumper harness between the vehicle wire harness electrical connector, and the Q8 control solenoid valve

assembly electrical connector.

3. Ignition ON, test for 8.3-9.3 volts between the ISS/OSS voltage circuit terminal B on the Q8 control solenoid valve assembly and ground at

the transmission case.

瀚慖f not within the specified range, replace the control solenoid valve assembly.

4. Perform the Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test (See:

Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/Control

Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test).

5. Inspect the machined teeth on the 1-2-3-4 and 3-5 clutch housing outer surface for damage or misalignment. Repair or replace as necessary.

6. If all of the above test normal, replace the B14A/B14C ISS/OSS assembly.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

* Perform the Input and Output Speed Sensor Replacement (See: Powertrain Management/Transmission Control Systems/Sensors and

Switches - Transmission and Drivetrain/Sensors and Switches - A/T/Transmission Speed Sensor/Service and Repair).

* Control solenoid valve assembly - refer to Control Module References (See: Testing and Inspection/Programming and Relearning) for

replacement, setup, and programming.

* Perform the Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test (See:

Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/Control

Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test).

* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and

Inspection/Programming and Relearning/Service Fast Learn Adapts) following all transmission related repairs.

Circuit/System Testing

1. Ignition OFF, remove the fuse that supplies B+ to terminal 56-X2 of the K20 ECM.

2. Disconnect the harness connector at the B26 crankshaft position sensor.

3. Test for 5 ohm or less between the low reference circuit terminal 1 and ground.

瀚慖f greater than the specified range, test for an open/high resistance in the low reference circuit. If the circuits/connections test normal,

replace the K20 ECM.

4. Install the fuse that supplies B+ to terminal 56-X2 of the K20 ECM.

5. Ignition ON, test for greater than 4.8 V between the 5 V reference circuit terminal 3 and the low reference circuit terminal 1.

瀚慖f less than the specified value, test the 5 V reference circuit for a short to ground or for an open/high resistance. If the

circuits/connections test normal, replace the K20 ECM.

瀚慖f greater than the specified value, test the 5 V reference circuit for a short to voltage. If the circuits/connections test normal, replace the

K20 ECM.

6. Test for 4.8-5.2 V between the signal circuit terminal 2 and ground.
