2001 Honda Accord MAP sensor: what it does and how to look after it

Based on Honda’s factory literature for the 1998–2002 Accord range (Helm service manual) and Honda’s electronic parts catalog, every 2001 Honda Accord—both the 2.3‑litre F23 four‑cylinder and the 3.0‑litre J30 V6—runs a Manifold Absolute Pressure (MAP) sensor. Honda’s OBD‑II fault list for this model also includes MAP‑related DTCs (P0106, P0107, P0108), underscoring that the MAP sensor is fitted and relevant to the 2001‑Honda‑Accord map‑sensor topic.

The MAP sensor’s job is straightforward: it measures intake manifold pressure so the ECU can calculate engine load. That data helps fine‑tune fuel delivery, ignition timing, and idle speed, and it also assists with altitude correction. On these Accords, the sensor sits on or near the throttle body/intake plenum and feeds the ECU a quick, precise signal for clean starts, smooth idling, and decent fuel economy on Aussie and Kiwi roads.

While the MAP sensor is a solid‑state part with no scheduled replacement, it still benefits from a bit of attention during servicing. Under the bonnet, check the electrical connector for corrosion or loose pins, inspect the O‑ring for hardening or cracks, and make sure the sensor port isn’t gummed up with oil mist. If cleaning is needed, use electronics‑safe spray directed at the port only—don’t drown the sensor. When refitting, seat the O‑ring properly and nip the screws to factory spec—no gorilla torque.

If the 2001 Accord starts feeling doughy off the line, idles roughly, drinks more petrol than it should, or throws a Check Engine Light, scan for codes. MAP‑related faults often show as:

• P0106 – MAP/Baro range–performance
• P0107 – MAP circuit low
• P0108 – MAP circuit high

Testing can be done with a scan tool or multimeter: expect a 5‑volt reference, a solid ground, and a signal that’s roughly low at idle (high vacuum) and climbs with throttle. If readings are off and the wiring checks out, replace the sensor with the correct part number—note that four‑cylinder and V6 units differ. After battery disconnect or sensor replacement, let the car idle with accessories off so the ECU can relearn, a short drive cycle helps it settle.

Treated right, the 2001‑Honda‑Accord map‑sensor quietly keeps the engine crisp, efficient, and happy over hundreds of thousands of kilometres.

Popular questions

Where is the MAP sensor on a 2001 Honda Accord?
On most 2.3‑litre models it’s mounted on the throttle body or directly on the intake plenum. On the 3.0‑litre V6 it’s on the upper intake manifold. Look for a small rectangular sensor with a three‑pin connector and an O‑ring seal.

What are the signs the MAP sensor is failing?
Typical clues are rough idle, hesitation, poor fuel economy, black smoke on acceleration, or a Check Engine Light with codes P0106–P0108. Sometimes it’s just a cracked O‑ring, a dirty port, or a wiring issue rather than the sensor itself.

Does the 2001 Accord use a MAF sensor instead of a MAP?
No. This generation Accord is a speed‑density system and uses a MAP sensor for load calculation. There’s no MAF sensor from the factory on the 2001 models.
