Primary/Secondary Shaft Pressure Sensor Inspection

1. Turn off all the electrical devices and ignition switch.
2. Disconnect the primary/secondary shaft pressure sensor

connector.

3. Check for resistance between the terminals of primary/secondary shaft pressure sensor as shown in the

table below at normal temperature.

HINT:
The inner parts of the sensor are triode and capacitor, and will be affected greatly by the environment and the
usage condition. Therefore, the actual measured value is within the specified value plus/minus 15% in the
table below.

Problem Symptoms Table

HINT:
Use the table below to help determine the cause of problem symptoms. Check each suspected area in
sequence. Repair or replace the faulty components, or adjust as necessary.

Diagnostic Help

1. Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC), and make it

communicate with vehicle electronic module by the data network.

2. Confirm that the malfunction occurs, and perform diagnosis tests and repair procedures.
3. If diagnostic trouble code (DTC) cannot be deleted, it is a current malfunction.
4. Only use a digital multimeter to measure the voltage of electrical systems.
5. Refer to any Technical Bulletin that may apply to the malfunction.
6. Visually check the related wire harnesses.
7. Inspect and clean all engine control module (ECM) grounds that are related to the latest DTC.
8. If multiple trouble codes were set, use the circuit diagrams and look for any common ground circuit or

power supply circuit applied to the DTC.

Intermittent DTC Troubleshooting

If malfunction is intermittent, perform the followings:
 Check if connectors are loose.
 Check if wire harnesses are worn, pierced, pinched or partially broken.
 Wiggle related wire harnesses and connectors and observe if signal is interrupted in the related circuit.
 If possible, try to duplicate the conditions under which the DTC was set.
 Look for the data that has changed or the DTC to reset during the wiggle test.
 Look for broken, bent, protruded or corroded terminals.
 Inspect the mounting areas of instrument cluster, wire harness or wire harness connector and so on for

damage, foreign matter, etc. that will cause incorrect signals.

Ground Inspection

Groundings are very important to entire circuit system, which are normal or not can seriously affect the entire
circuit system. Ground points are often exposed to moisture, dirt and other corrosive environments. Corrosion
(rust) and oxidation can increase load resistance. This situation will seriously affect the normal operation of
the circuit. The operations to check the ground points are as follows:
1. Remove the ground bolt or nut.
2. Check all contact surfaces for tarnish, dirt and rust, etc.
3. Clean as necessary to ensure that contacting is in a good condition.
4. Reinstall the ground bolt or nut securely.
5. Check if add-on accessories interfere with the ground circuit.
6. If several wire harnesses are crimped into one ground eyelet terminal, check if they are installed correctly.

Make sure all wire harnesses are clean, securely fastened and providing a good ground path.
