Check oil pressure sensor over entire pressure range:
1. Disassemble sensor and connect it to a gauged
pressure source.
2. Connect ohmmeter and pressurize sensor. Read
and record pressure and resistance at different spots
over the entire pressure range.
3. Compare pressure and resistance values with chart.
If values are not within tolerance range at one spot,
replace sensor.
06.10.05.07 Check coolant temperature sensor, B16
To check the coolant temperature sensor, make the
following test with connected ohmmeter. In case of
failure, replace the sender.
1. Compare resistance value and ambient temperature
to curve of diagram. Range of tolerance is ± 10 %.
