2.7 Bar MAP Sensor for HSV VF LSA Cruze JH Barina Trax - LS2 LS3 Boost Upgrade
Direct Fit Replaces 12592525
BRAND NEW *OEM Quality* 2.7 Bar MAP Sensor to suit the HSV VF 6.2L LSA supercharged V8, Holden Cruze JH, Barina TM RS and Trax TJ turbo petrol engines - also a popular boost upgrade for LS2 and LS3 V8 builds.
Boost reading wrong, check engine light with a MAP code, or flat spots under load on your turbo or supercharged engine? A failing MAP sensor is a common cause. Packed and shipped from Cranbourne VIC.
TO SUIT
- For HSV Clubsport, GTS, Maloo and Senator VF 6.2L LSA Supercharged V8 (2013-2017)
- For Holden Cruze JH 1.4L Turbo A14NET (2011-2016) and 1.6L SRi Turbo A16LET (2013-2016)
- For Holden Barina TM RS 1.4L Turbo A14NET (2013-2016)
- For Holden Trax TJ 1.4L Turbo B14NET (2014-2020)
FITMENT CHECK
This is a 2.7 bar (20 to 270 kPa) sensor with a 3-pin Compact connector and single mounting bore. On a naturally aspirated LS2 or LS3 V8 it is NOT a direct replacement for the factory 1-bar sensor - it is a boost conversion part and the ECU must be retuned to the 2.7 bar calibration. Fitted to a stock engine without a retune, the engine will run poorly. The Opel Astra J 1.4 Turbo uses a different sensor (0261230263) - this one does not suit it.

ABOUT THIS SENSOR
The manifold absolute pressure sensor measures the pressure inside the intake manifold, including boost on turbocharged and supercharged engines. The ECU uses this reading to calculate engine load, then sets fuelling, ignition timing and boost control from it.
A 2.7 bar range lets the sensor read up to about 1.7 bar of boost, which is why it is used on factory forced-induction engines and in boost conversions. When the sensor fails or drifts, the ECU miscalculates load and the engine runs rich or lean, loses power or drops into limp mode.
COMMON SYMPTOMS OF FAILURE
- Check engine light with a MAP sensor code (P0105 to P0108)
- Hesitation or flat spots under boost
- Reduced power or limp mode
- Poor fuel economy or black smoke
- Rough idle or stalling

What fault codes does a faulty MAP sensor trigger?
A faulty MAP sensor typically triggers codes P0105 to P0109. P0105 indicates a circuit malfunction, P0106 indicates the signal is out of range, P0107 and P0108 indicate the signal is too low or too high respectively, and P0109 indicates an intermittent circuit fault. These codes combined with symptoms such as poor idle and black smoke are strong indicators of MAP sensor failure.
How do I test a MAP sensor?
With an OBD2 scanner in live data mode, the MAP sensor should read close to atmospheric pressure (around 101 kPa) with the engine off, and drop to 30 to 50 kPa at idle with the engine running due to manifold vacuum. Under wide open throttle the reading should rise back toward atmospheric. A sensor that reads flat or does not respond to throttle changes has failed. You can also test supply voltage and signal output with a multimeter.
Can I drive with a faulty MAP sensor?
You can drive short distances but engine performance will be noticeably degraded. The ECU uses the MAP sensor to calculate fuel delivery - a faulty sensor causes incorrect fuelling which leads to poor economy, rough running, and increased emissions. On turbocharged engines a faulty MAP sensor can also prevent boost control from operating correctly. Replace it as soon as possible to avoid further damage.
What does a MAP sensor do?
The Manifold Absolute Pressure (MAP) sensor measures intake manifold pressure to help the ECU calculate the correct fuel and ignition timing. It is critical for engine efficiency, particularly on turbocharged and supercharged vehicles.
What are the symptoms of a faulty MAP sensor?
Symptoms include poor acceleration, rough idle, excessive fuel consumption, black smoke, engine hesitation, and a Check Engine light with codes P0105-P0109. Turbocharged vehicles may also experience boost control issues.
What is the difference between a MAP sensor and a MAF sensor?
A MAF (Mass Air Flow) sensor directly measures the mass of air entering the engine. A MAP sensor measures manifold pressure and the ECU calculates air mass from that reading. Many vehicles use one or the other; some use both. They are not interchangeable.
