Parts for your 2000 Daihatsu Yrv-Map sensor

2000 Daihatsu YRV MAP sensor: purpose, location, and service tips

Based on the Daihatsu YRV M200 Series workshop manual (Engine Management/EFI section), the Daihatsu Electronic Parts Catalogue for the M200/M201 YRV (listing “Sensor, Pressure” for the K3‑VE and K3‑VET engines), and Denso’s MAP sensor application guides for late‑90s/early‑2000s Asian models, the 2000 Daihatsu YRV does use a MAP (Manifold Absolute Pressure) sensor. On turbo K3‑VET models it also serves as the boost pressure sensor. So, the MAP sensor is absolutely relevant to this vehicle.

On a 2000 Daihatsu YRV, the MAP sensor is a small Denso three‑pin unit that reads the vacuum (and on the turbo, boost) in the intake manifold. The ECU combines this pressure reading with intake air temperature and engine speed to figure out how much fuel to inject and where to set ignition timing. It’s a simple, reliable speed‑density setup that suits our mixed Aussie and Kiwi driving—everything from city crawls to long open‑road kilometres.

When a MAP sensor goes out of whack, the YRV can feel doughy off the line, idle roughly, or chew through more fuel than it should. It may light up the check‑engine lamp with codes like P0106, P0107, or P0108. Before ordering parts, a quick check with a scan tool under the bonnet is gold: with key‑on/engine‑off, the sensor should read close to local barometric pressure, at warm idle, expect a healthy vacuum reading. If numbers look odd, verify the 5V reference, ground, and signal at the plug, and make sure the vacuum hose (where fitted) isn’t split or loose.

Replacement on the YRV is straightforward. For K3‑VE models, the sensor is often mounted on the firewall or intake area with a small vacuum hose to the manifold, on K3‑VET it’s typically on or near the manifold/intercooler piping. Steps are simple: unplug the connector, remove the retaining screw, gently pull the sensor, and check the hose and port for oil sludge or carbon. Refit the new unit, ensure the hose is snug and crack‑free, click the connector back on, then clear any codes and take it for a drive so the ECU can relearn trims.

As part of routine servicing, it’s smart to:

• Inspect the MAP sensor plug and wiring for chafing or corrosion.
• Check the vacuum hose for perishing, soft spots, or oil contamination.
• Avoid spraying harsh cleaners directly into the sensor port—if it’s contaminated, replace it.

Look after the MAP sensor and the YRV rewards you with crisp throttle response, steady idle, and better economy across your daily kilometres.

Where is the MAP sensor on a 2000 Daihatsu YRV?

On most K3‑VE (non‑turbo) cars it’s a small Denso three‑pin unit mounted near the intake manifold or firewall with a short vacuum hose to the manifold. On K3‑VET turbo models it’s typically fixed to the manifold or close to the intercooler piping and reads both vacuum and boost.

Can a YRV MAP sensor be cleaned, or should it just be replaced?

If the port is lightly oily, you can carefully wipe the outside and ensure the hose and manifold port are clean. Avoid blasting solvents into the sensor—damage is easy. If it’s contaminated internally or readings are unstable, replacement is the safer bet.

What symptoms point to a failing MAP sensor on a YRV?

Common signs include rough idle, hesitant take‑off, poor fuel economy, black exhaust smoke, and a check‑engine light with codes like P0106–P0108. Always rule out vacuum leaks or split hoses before condemning the sensor.
