178 / 178 guides

Sensor orientation guides · MAF, MAP, EGR and DPF

General orientation only, NOT verified locations for a specific vehicle. Exact identification requires engine code, year and technical documentation.

MAF · Mass airflow sensor

Usually on the intake duct after the air filter and before the turbo or throttle, if fitted.

P0100 P0101

MAP · Manifold pressure sensor

Usually on the intake manifold or charge-air pipe. A separate boost pressure sensor may also be fitted.

P0106 P0299

EGR · Exhaust gas recirculation valve

Near the exhaust-to-intake recirculation path; some engines have EGR coolers and multiple circuits.

P0401 P0402

DPF · DPF differential pressure sensor

Often in the engine bay or underbody, connected by two small pressure lines across the particulate filter. Exact placement depends on engine.

P2453 P2002

Do not disconnect sensors, DPF lines or hot components to identify them. Codes are diagnostic examples, not proof of a fault.
