2020 Toyota Camry MAP sensor: what it does, why it matters, and how to look after it

Based on Toyota’s technical literature, the 2020 Toyota Camry does use a MAP (Manifold Absolute Pressure) sensor. The Toyota Repair Manual for the 2018–2022 Camry (A25A-FKS 2.5‑litre, A25A‑FXS hybrid, and 2GR‑FKS 3.5‑litre V6) includes diagnostic sections for the Manifold Absolute Pressure Sensor (often labelled “PIM”/Vacuum Sensor) with DTCs P0106, P0107 and P0108. Toyota’s Electronic Parts Catalogue also lists a “Sensor, Vacuum (Manifold Absolute Pressure)” for these engines. So, yes—this Camry runs both a MAF and a MAP sensor.

On the 2020 Camry, the MAP sensor helps the engine computer understand real-time intake manifold pressure. That pressure snapshot lets the ECU fine-tune fuelling and ignition, cross-check the MAF signal, adjust for altitude, steady the idle, manage EGR flow on relevant variants, and sharpen throttle response during quick on‑off driving. It’s a small solid‑state sensor mounted to the intake manifold (with an O‑ring seal) near the throttle body on the four‑cylinder, and in a similar manifold location on the V6.

It isn’t a scheduled replacement item in Australia or New Zealand, but it’s smart to keep an eye on it whenever the car is in for servicing—especially if there’s a Check Engine light, rough idle, sluggish performance, or higher‑than‑usual petrol use. Technicians usually verify MAP readings with a scan tool: with key on/engine off, the reading should be close to local barometric pressure (about 100 kPa at sea level), at warm idle, many naturally aspirated engines will show roughly 30–45 kPa.

If replacement is needed, the job is generally straightforward: unplug the connector, remove the fixing screw(s), lift out the sensor, and install a new unit with a fresh O‑ring. Avoid twisting or levering against the plastic body. Before refitting, check for oil mist or carbon build-up at the manifold port and clean it carefully if required. After installation, clear any fault codes and take a short drive so the ECU can relearn trims. Because these sensors are delicate, don’t spray harsh cleaners into the sensor port—if it’s contaminated internally, replacement is the reliable fix.

• Common fault codes: P0106 (range/performance), P0107 (low input), P0108 (high input).
• Quick checks: inspect the connector, wiring, and the O‑ring, confirm no vacuum leaks at the manifold, compare MAP kPa to ambient with engine off.
• Good practice: have it inspected during major services (e.g., every 60,000–90,000 km) or whenever drivability issues pop up.

Popular questions about the 2020 Toyota Camry MAP sensor

Does the 2020 Camry have both a MAF and a MAP sensor?

Yes. The 2020 Camry uses a MAF for primary airflow measurement and a MAP to track manifold pressure for load calculation, altitude correction, and diagnostic cross‑checks. Toyota’s repair manual includes MAP‑related DTCs, confirming it’s fitted across the main engines.

Where is the MAP sensor on a 2020 Toyota Camry?

It’s mounted on the intake manifold with a small O‑ring seal. On the 2.5‑litre four‑cylinder it’s near the throttle body under the bonnet, on the 3.5‑litre V6 it’s also on the manifold but the exact spot varies—look for a compact sensor with a single electrical connector.

What are common MAP sensor symptoms and quick DIY checks?

Watch for a Check Engine light, rough idle, poor fuel economy, or flat spots. With a scan tool, key on/engine off should show around ambient pressure (~100 kPa at sea level). At idle, expect roughly 30–45 kPa. Also check the connector, wiring, O‑ring, and nearby vacuum leaks.
