BRAND NEW *OEM Quality* MAP / boost pressure sensor to suit Holden Colorado RG 2.8L and 2.5L Duramax turbo diesel.

A failing boost sensor on the Colorado drops the engine into limp mode with a sudden loss of turbo power. This 3-bar sensor restores accurate boost readings and is dispatched same day before 12pm.

TO SUIT

Built for the Holden Colorado RG and Colorado 7 from 2012 to 2020 with the 2.8L LWH and LWN Duramax turbo diesel, plus the 2.5L LVN, and the Trailblazer RG 2.8L from 2016. On these engines the sensor sits on the intercooler pipe and reads boost pressure for the ECU. The same sensor also fits the Astra AH CDTI, Cruze JH and Barina TM 1.4 turbo and Malibu EM diesel - see the full list.

1 x MAP / boost pressure sensor, 3-bar range, 4-pin plug.

ABOUT THIS SENSOR

The MAP sensor measures intake manifold pressure so the ECU can calculate air mass and set fuel delivery. On the Duramax it also lets the ECU control the variable vane turbo and stop overboost.

When the reading drifts or drops out, the ECU protects the engine by cutting boost - the Colorado feels flat, smokes under load and throws boost fault codes. Direct connector match with no wiring modification.

COMMON SYMPTOMS OF FAILURE

Limp mode and sudden loss of power under load

Fault codes P0236 / P0237 / P0238 (boost sensor)
Black smoke and poor throttle response
Higher fuel consumption

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.
