Parts for your 2014 Holden Barina-Map sensor

2014 Holden Barina MAP sensor — what it does and how to look after it

Yes, the 2014 Holden Barina is fitted with a MAP (Manifold Absolute Pressure) sensor. This is confirmed across technical sources including GM Service Information (SI) for the T300 Sonic/Aveo platform (on which the Barina TM is based), the Holden Barina TM Workshop Manual (Engine Controls), and ACDelco/Delphi parts catalogues listing MAP sensors for 2011–2016 Barina variants. On the RS 1.4‑turbo, there’s a manifold pressure sensor plus a charge‑air/boost pressure sensor, the 1.6‑litre models use a manifold pressure sensor for load calculation.

On this Barina, the MAP sensor measures the absolute air pressure inside the intake manifold. The engine control module uses that pressure, along with intake air temperature and engine speed, to work out engine load (speed‑density strategy). That helps it dial in the right fuel and ignition timing, run stable idle control, manage EGR/evap functions, and, on the RS, monitor and limit boost. When the MAP reads cleanly, the Barina pulls smoothly, starts easily, and keeps fuel economy in check around town and on the open road.

As part of regular servicing, the MAP sensor doesn’t need scheduled replacement, but it should be checked. Under the bonnet, confirm the connector is snug, the harness isn’t chafed, and the sensor’s O‑ring isn’t torn. A scan tool can quickly verify it’s happy: with ignition on/engine off it should read close to local barometric pressure (roughly 100 kPa at sea level), and it should drop at idle and rise crisply with a throttle blip. Oil mist from the PCV system or dust from a leaking intake can contaminate the sensing port, so keeping the air filter and intake plumbing in good nick helps the MAP live a long life.

• Common MAP issues show up as rough idle, flat spots, high fuel use, hard starting, or a check‑engine light (often P0106, P0107, P0108).
• If readings are erratic or out of range, replacement is the fix. It’s a simple job: unplug, remove the retaining screw, swap the sensor and O‑ring, refit, and clear codes. Tighten only to the manufacturer’s spec—snug, not gorilla tight.
• A light mist of electronics‑safe cleaner can clear light contamination, but if the sensor’s cracked, oil‑soaked, or still misbehaving, fit a quality OEM‑equivalent unit.

Pro tip for RS owners: there are two pressure sensors in the system—make sure the right one is being tested or replaced.

FAQs

Where is the MAP sensor on a 2014 Barina?
The 1.6‑litre sits on the intake manifold near the throttle body. On the RS 1.4‑turbo, there’s a T‑MAP on the manifold and a separate charge‑pressure sensor on the intercooler pipe—don’t mix them up.

What fault codes point to a bad MAP sensor?
Typical codes are P0106 (range/performance), P0107 (low input), and P0108 (high input). You may also see drivability symptoms like rough idle and heavy fuel use alongside these codes.

Can a MAP sensor be cleaned, or should it be replaced?
A gentle spray of electronics‑safe cleaner can help if there’s light oil film. If the sensor is cracked, soaked with oil, or the readings stay flaky, replacement is the reliable, time‑saving option.
