PR059 INTAKE AIR TEMPERATURE

INSTRUCTIONS

Special notes: Carry out the checks only if the parameter is inconsistent.

Check the condition of the intake air pressure / temperature sensor connector.

Replace the sensor if necessary.

Measure the resistance between terminals 1 and 2 of the intake air pressure / temperature sensor:

Theoretical values: 8950 to 9901 Ω at -10 °C
7054 to 7784 Ω at -5 °C
5605 to 6169 Ω at 0 °C
3618 to 3964 Ω at 10 °C
2400 to 2620 Ω at 20 °C
1645 to 1787 Ω at 30 °C

Replace the intake air pressure - temperature sensor if not as specified.

AFTER REPAIR

Address any faults declared by the diagnostic tool. Clear the ECU memory.

Carry out a road test followed by a further check with the diagnostic tool.

PR064 COOLANT TEMPERATURE

INSTRUCTIONS

Special notes: Carry out the checks only if the parameter is inconsistent.

Check the condition of the coolant temperature sensor connector.

Replace the sensor if necessary.

Measure the resistance between terminals 2 and 3 of the coolant temperature sensor.

Theoretical values: 12.46 kΩ ± 1128 Ω at -10 °C.
2252 Ω ± 112.6 Ω at 25 °C.
811.4 Ω ± 38.4 Ω at 50 °C.
282.6 Ω ± 7.83 Ω at 80 °C.

Replace the coolant temperature sensor if not as specified.

AFTER REPAIR

Address any faults declared by the diagnostic tool. Clear the ECU memory.

Carry out a road test followed by a further check with the diagnostic tool.
