Parts for your 1998 Nissan Navara-Map sensor

1998 Nissan Navara MAP sensor — is it actually there?

For a 1998 Nissan Navara (D22), a MAP sensor generally isn’t fitted or used. On Aussie and Kiwi-delivered models of that year, the common engines were the KA24E 2.4 petrol and the QD32 3.2 diesel. Technical references show these setups don’t rely on a manifold absolute pressure sensor for engine load. Instead, the KA24E uses a Mass Air Flow (MAF) sensor ahead of the throttle body, and the QD32 diesel runs a mechanically governed injection pump without an engine control module, so there’s nothing to read MAP in the first place.

Factory sources that back this up include the Nissan D22 Series Workshop Manual (1997–2000): the Engine Control (EC) section for KA24E lists a MAF as the primary load sensor and makes no provision for a MAP sensor. The Diesel Engine section for the QD32 details a mechanical VE-type pump with no ECU. Nissan FAST parts cataloguing for D22 (1997–1999) also lists a MAF sensor (e.g., 22680- prefix) but no manifold pressure sensor for those VIN ranges. Aftermarket data sets such as Autodata and Ellery’s/Gregory’s manuals for D22 of the same years align with this—no MAP on those engines.

Why no MAP? Nissan’s strategy at the time leaned on MAF-based fuelling for the petrol KA24E, which directly measures the air entering under the bonnet. For the early D22 diesels, fuelling is controlled mechanically, so there’s no electronic engine management to interpret manifold pressure. A MAP or boost sensor starts showing up on later, electronically controlled and turbocharged Navara engines (like some YD25 and ZD30 variants), not on the typical 1998 line-up.

Getting mixed messages from a parts search? It’s common for “MAP sensor” listings to appear because parts catalogues blur D22 year ranges. If a technician has called out a “MAP” on a 1998 KA24E, they’re likely talking about the MAF on the intake duct. For maintenance, that means keeping the air filter clean, checking for split intake hoses, and only cleaning the MAF with proper MAF-safe cleaner—never with general solvents. On QD32 diesels, good vacuum hoses and boost plumbing (where applicable) matter, but there’s no MAP sensor to replace.

• KA24E 2.4 petrol (1998 D22): MAF sensor used, no MAP.
• QD32 3.2 diesel (1998 D22): Mechanical injection, no ECU, no MAP.
• Later D22 electronic turbo models: may use a MAP/boost sensor—different years/engines.

Popular questions about a 1998 Nissan Navara “MAP sensor”

Does a 1998 Nissan Navara have a MAP sensor?
On most 1998 D22 models sold in Australia and New Zealand, no. The KA24E petrol uses a MAF, and the QD32 diesel is mechanically controlled without an ECU. A MAP/boost sensor appears on later, electronically managed turbo engines, not typically on the ’98s.

Where would a MAP sensor be on a 1998 Navara?
If the ute is truly a 1998 KA24E or QD32, there usually isn’t one to find. Owners sometimes confuse the MAF (on the intake snorkel/air duct) with a MAP. If the vehicle has had an engine swap to a later turbo-diesel with electronic control, a MAP/boost sensor would normally mount on or near the intake manifold or firewall with a hose to the manifold.

My parts search shows a MAP sensor for 1998—what gives?
Many online catalogues lump all D22 years together. That pulls in parts for later engines that don’t apply to early D22s. Check the engine code on the build plate or rego details. If it’s KA24E or mechanically injected QD32, you’re chasing a MAF or vacuum-related component, not a MAP.
