BRAND NEW *OEM Quality* 1-bar barometric MAP Sensor with integrated air temperature sensor to suit the Ford Transit VM 2.3L petrol and diesel engines and the Ford Ranger PJ / PK 2.5L petrol.

If your Transit or Ranger is running rough or showing intake pressure fault codes - this is the direct-fit barometric replacement for the inlet manifold position. Most orders dispatched same-day from Melbourne.

TO SUIT

This is the 1-bar barometric MAP sensor located on the inlet manifold. Primary fitment is the Ford Transit VM 2.3L GZFA petrol from 2006 to 2008 and the Ford Ranger PJ / PK 2.5L Duratec petrol from 2006 to 2011. Also suits Ford Transit VM diesel variants (QVFA / H9FB / SRFA-E / CVRB-E) in the atmospheric sensor position on the inlet manifold. Connector: 4-pin.

FITMENT CHECK

This is the 1-bar atmospheric sensor on the inlet manifold - not the 3-bar boost pressure sensor on the intercooler. Ford Transit diesel models carry both sensors. If you need the 3-bar boost pressure MAP sensor for the charge air pipe see MP245-1503280 instead.

PACKAGE INCLUDES

1 x 1-bar barometric MAP Sensor with integrated air temperature sensor. 4-pin connector. Inlet manifold / plenum position.

ABOUT THIS SENSOR

The barometric MAP sensor measures atmospheric pressure at the inlet manifold and sends the reading to the ECU for fuel delivery and ignition timing calculations. On these engines the unit also integrates an air temperature sensor - both signals handled by a single plug-in component.

This is the 1-bar atmospheric position sensor reading up to approximately 105 kPa. It is distinct from the 3-bar boost pressure sensor found on the intercooler of turbocharged diesel variants - both can fail independently.

COMMON SYMPTOMS OF FAILURE

Check engine light or EML warning active
Rough idle or hesitation under acceleration
Poor fuel economy and reduced power output
Hard starting or stalling at idle
Fault codes P0105 / P0107 / P0108 / P1107
Incorrect fuel trim readings in scan tool

NOTE: This is the 1-bar barometric MAP sensor on the inlet manifold - not the 3-bar boost pressure sensor on the intercooler. See MP245-1503280 for the 3-bar boost sensor.

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.
