Parts for your 2007 Holden Barina-Map sensor

2007 Holden Barina MAP sensor — what it does and how to look after it

Based on Holden’s TK Barina workshop material (GM Global Service Information) and equivalent 2007 Chevrolet Aveo/Kalos T250 service data, plus parts listings from ACDelco and Bosch, the 2007 Holden Barina is fitted with a MAP (Manifold Absolute Pressure) sensor. This model runs a speed–density system, so there’s no MAF, the ECU relies on the MAP sensor for load calculation.

On the 2007 Barina, the MAP sensor reads intake manifold pressure and, together with intake air temperature and engine speed, lets the ECU figure out how much air is going in. That’s how it sets fuel delivery and ignition timing. It also provides a barometric reference at key-on, helping the car adapt from sea level to alpine roads without fuss. When the MAP-sensor is healthy, cold starts are cleaner, idle is steadier, and fuel economy stays on the right side of the ledger.

The sensor is a small, three‑pin unit mounted directly to the intake manifold with an O‑ring seal (on TK/T250 it’s typically up top near the throttle body). There’s no fixed replacement interval in GM literature, but it’s a known wear item. Common fault codes include P0106 (range/performance), P0107 (low input) and P0108 (high input), often accompanied by rich running, a lumpy idle, hard starting, or higher‑than‑usual fuel use.

As part of regular servicing, a workshop should do a quick health check with a scan tool. Expected readings: with ignition on/engine off, around local barometric pressure (roughly 95–101 kPa at sea level), at warm idle, typically 28–40 kPa, with a quick throttle snap, pressure should rise and fall crisply. Electrical checks should confirm a solid 5 V reference, good ground, and a signal that swings roughly 0.5–4.5 V with load.

Cleaning is limited but sometimes worthwhile: if there’s light oil mist, a brief spray with electronics or MAF-safe cleaner and a gentle air dry can help. Avoid poking the sensing port and don’t flood it with solvent. Inspect the O‑ring for flattening, check the loom for brittle insulation, and make sure the connector isn’t green with corrosion.

When replacement’s needed, quality counts. Genuine ACDelco or reputable brands like Bosch/Delphi tend to play nicest with the Barina’s ECU. After fitting, clear any codes and perform an idle relearn if required. A quick vacuum‑leak sweep around the manifold is a smart add‑on to keep fresh sensors from masking bigger issues.

• Typical symptoms: rough idle, sluggish throttle, high fuel use, MIL on with P0106/P0107/P0108
• Location: intake manifold, three‑pin plug, O‑ring seal
• Service tip: verify readings with a scan tool before condemning the sensor

Popular questions

Does the 2007 Holden Barina use a MAP or a MAF?
This model uses a MAP sensor and no MAF. The TK/T250 platform runs a speed–density strategy, with the ECU calculating airflow from manifold pressure, intake air temperature and rpm.

Where is the MAP sensor on a 2007 Barina?
It’s mounted on the intake manifold, typically on the upper side near the throttle body. Look for a small black sensor with a three‑pin connector and an O‑ring seal into the manifold.

What codes point to a dodgy MAP sensor on a Barina?
The usual suspects are P0106 (range/performance), P0107 (low input) and P0108 (high input). These may pair with rough idle, stalling, rich running or poor fuel economy. Always rule out wiring faults or vacuum leaks before replacing the sensor.
