BRAND NEW *OEM Quality* Intake Air Temperature Sensor to suit Holden Monaro V2 VZ 5.7L V8 LS1 2001 to 2006.

If your Monaro is hunting at idle or throwing an IAT fault code - this push-fit sensor drops straight into the factory grommet on the intake pipe and has your LS1 reading air temperature accurately again. Dispatched same-day from Melbourne.

TO SUIT

This sensor suits the Holden Monaro V2 with the 5.7L V8 LS1 from December 2001 through August 2003, and the Monaro VZ LS1 from September 2004 through July 2006 at 225kW, 235kW, 245kW, and 260kW outputs. Push-fits into the rubber grommet on the factory air intake pipe - no programming or tuning required.

ABOUT THIS SENSOR

The IAT sensor lives in the air intake pipe between the airbox and the throttle body. The ECU reads it continuously to adjust fuel delivery and ignition timing based on incoming air density. On the LS1 Monaro, accurate air temperature data is especially important under hard acceleration where detonation margin is tight.

A failed IAT sensor forces the ECU onto a fixed air temperature assumption. On the Monaro this usually shows as rich cold-start running, hesitation on tip-in, or a P0112/P0113 fault - all of which clear once you replace this sensor.

COMMON SYMPTOMS OF FAILURE

Check engine light on - fault codes P0112 / P0113 (IAT circuit low/high)
Hesitation or stumble on acceleration especially when cold
Rich running or black smoke on cold start
Rough idle or extended cold-start warm-up
Poor fuel economy
Scan tool showing fixed or erratic IAT reading

What does an intake air temperature (IAT) sensor do?

The intake air temperature (IAT) sensor measures the temperature of air entering the engine and sends this data to the ECU. Cold dense air contains more oxygen than warm thin air and requires more fuel for the same combustion result. The ECU uses IAT data alongside manifold pressure or airflow data to calculate the correct fuel injection quantity and ignition timing for the current air temperature conditions. On many vehicles the IAT sensor is integrated into the mass airflow (MAF) sensor housing.

What are the symptoms of a failing air temperature sensor?

Common symptoms include poor fuel economy as the ECU miscalculates fuel delivery based on incorrect temperature data, rough idle or hesitation under acceleration, black smoke from the exhaust due to over-fuelling, hard starting particularly from cold, and a Check Engine light with IAT circuit fault codes P0110 to P0114. Some vehicles may also experience difficulty starting because the ECU cannot correctly calculate the cold start enrichment required.

How do I test an air temperature sensor?

The IAT sensor is a thermistor that changes resistance with temperature. With a cold engine (ambient temperature) the resistance is high - typically 2,000 to 3,000 ohms at 20 degrees C. As temperature rises resistance falls. You can test resistance with a multimeter at the sensor connector and compare against the temperature/resistance chart in your vehicle service manual. An OBD2 scanner showing an IAT reading that does not match ambient temperature when the engine is cold is also a strong indicator of failure.

Is the IAT sensor the same as the MAF sensor?

No - they are different sensors, although on many modern vehicles the IAT sensor is built into the MAF sensor housing as a combined unit. The MAF sensor measures the mass of air entering the engine using a hot wire element. The IAT sensor measures the temperature of that air using a thermistor. If you have a combined MAF/IAT unit that fails, you typically need to replace the complete assembly. Use the Vehicle Part Finder to confirm which type is fitted to your vehicle.

Can a faulty IAT sensor cause my vehicle to fail an emissions test?

Yes. An incorrect IAT reading causes the ECU to miscalculate fuel delivery, typically resulting in a rich running condition with higher CO and hydrocarbon emissions. An active fault code from the IAT sensor will also cause most roadworthy and emissions inspection systems to flag the vehicle as failing the on-board diagnostics check before exhaust emissions are even measured. Resolve any IAT sensor faults before presenting for an emissions test.

Does the IAT sensor need to be reset or calibrated after replacement?

No - the IAT sensor is a passive thermistor requiring no calibration or programming. It is a direct plug-in replacement. Clear any stored fault codes with an OBD2 scanner after fitting the new sensor. The ECU will immediately begin reading the new sensor data and adjust fuelling accordingly. If the vehicle has been running rich due to the faulty sensor, fuel trim values will self-correct over several drive cycles.
