BRAND NEW *OEM Quality* 2.5 Bar boost pressure sensor to suit Skoda Fabia Octavia Superb Yeti Rapid and Roomster with 1.8T and 2.0T turbocharged engines.

Skoda shares the VAG MAP sensor across all turbocharged models - whether a city Fabia or a touring Superb 2.0 TDI the same OEM 038906051B is used. This direct-fit replacement covers the full Skoda range. Dispatched from Victoria.

TO SUIT

Suits Skoda Fabia 5J with 1.4 TSI (CAVD CNVA) and Octavia 1Z with 1.8 TSI (CDAB CDAA) and 2.0 TDI (CBDA CBDB). Also suits Superb 3T with 1.8 TSI (CDAB) and 2.0 TSI (CDLF CCZA) and Yeti 5L with 1.4 TSI (CAVD) and 1.8 TSI (CDAB). The 1.8 TSI CDAB engine on the Octavia is known for MAP sensor failure at 100000-120000 km coinciding with carbon buildup on intake valves that traps heat near the sensor mount. Verify OEM 038906051B before ordering.

ABOUT THIS SENSOR

On the Skoda Octavia 1Z and Superb 3T the MAP sensor for the 1.8 TSI sits close to the charge-cooled intake manifold. The 1.8 TSI CDAB engine is documented in Skoda communities for MAP sensor failure at around 100000-120000 km - often coinciding with carbon buildup on the intake valves that creates heat pockets near the sensor mounting point and accelerates diaphragm fatigue.

The Skoda Yeti 1.4 TSI with ACT (Active Cylinder Technology) is particularly sensitive to MAP sensor accuracy because cylinder deactivation decisions rely on accurate load calculation. A drifting MAP sensor on the Yeti ACT can cause erratic cylinder reactivation and a noticeable judder at light throttle that is often misdiagnosed as an engine mount fault.

COMMON SYMPTOMS OF FAILURE

Fault codes P0105 P0107 P0108 P0234
Limp mode on Octavia 1.8 TSI under motorway overtaking
Erratic cylinder deactivation on Yeti 1.4 TSI ACT
Hesitation at low throttle on Fabia 1.4 TSI in city driving
Superb 2.0 TDI limp mode under towing load
Fuel consumption increase across all models

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.
