Removal and installation the crankshaft position sensor
Attention.
- Presence of foreign particles (for example, steel filings) on the crankshaft position sensor leads to malfunction of the sensor, since extraneous swirls are created, which negatively affects the engine management system. Make sure that there are no foreign particles on the crankshaft position sensor.
- Install the crankshaft position sensor only as described below. Otherwise, some engine management functions may be impaired, such as ignition timing or fuel injection.
1. Disconnect the negative battery terminal.
2. Raise the car on a lift.
3. Perform the following procedures to facilitate access:
- Remove the service port cover (installed on the front protective pan of engine No.2) used to remove the oil filter.
- Remove the front mudguard.
4. Disconnect the crankshaft position sensor connector.
5. Remove the crankshaft position sensor.
Note:replace the part with a new one after each removal.
6. Installation is carried out in the reverse order of removal.
Checking the crankshaft position sensor
Visual inspection
Attention.
- Presence of foreign particles (for example, steel filings) on the crankshaft position sensor leads to malfunction of the sensor, since extraneous swirls are created, which negatively affects the engine management system. Make sure that there are no foreign particles on the crankshaft position sensor.
- Install the crankshaft position sensor only as described below. Otherwise, some engine management functions may be impaired, such as ignition timing or fuel injection.
1. Remove the crankshaft position sensor.
2. Make sure there are no metal filings on the sensor. If filings are found on the sensor, remove them.
Checking voltage
Caution: If the wiring or sealed connectors are damaged, water entering the connector may cause the sensor to malfunction. To prevent this, keep the wiring and sealed connectors in good condition.
1. Start the engine at idle speed.
2. Using an oscilloscope, measure the output voltage of the crankshaft position sensor. If the obtained values are not within the norm, replace the crankshaft position sensor.
