PR059 INLET AIR TEMPERATURE
NOTESSpecial notes:
This parameter is invalid and set at -50°C for K9K 728 engines.
Check the condition of the air temperature - pressure sensor connections.
If necessary replace the sensor.
Measure the resistance between tracks 1 and 2 of the air temperature - pressure 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 air temperature - pressure sensor if it is not in order.

TEST 11
CONTINUED
High pressure circuit check
Note:
Depending on the vehicle type, the best visual access will be
either from above or from below.
Visually inspect the condition of the following components:
– the compressor outlet pipe to the turbocharging air cooler (the
turbocharging air cooler does not exist for all engines),
– outlet pipe of the turbocharging air cooler to the inlet manifold,
– inlet manifold,
– temperature and pressure sensors.
Is one of these components incorrect (disconnected, cut,
bent, pierced or kinked pipes)?Replace the defective parts (see
MR 364 (Mégane II) or 370 (Scénic
II), Mechanical, 12B,
Turbocharging).
Exhaust system check
Visually inspect the condition of the following engine sections:
– from the exhaust manifold circuit to the turbocharger turbine,
– from the turbine outlet pipe to the end of the exhaust pipe,
– from the inlet manifold to the EGR valve
– check that the temperature and pressure sensors are
connected.
Do some of these components have black or white marks on
them? Replace the defective parts (see
MR 364 (Mégane II) or 370 (Scénic
II), Mechanical, 12B,
Turbocharging).
Run TEST 10: Turbocharger control solenoid valve check.
