DENSO PE01-13-350 Pompa Alta Pressione Mazda Skyactiv-G 2.0L 2.5L
PE01-13-350, PE01-13-350A, PE01-13-350B, PE01-13-350C, PY01-13-350Integrated Solenoid Suction Control Spill Valve (SCV)-200 barPanoramica Prodotto
The Denso PE01-13-350 (Mazda OE PE01-13-350A / PE01-13-350B / PY01-13-350) is the genuine original equipment high-pressure fuel pump for Mazda Skyactiv-G 2.0L and 2.5L naturally aspirated and turbocharged engines. Driven by the exhaust camshaft via an anti-friction bucket lifter, this Denso single-piston pump delivers up to 200 bar (20 MPa) injection pressure. Standard fitment on Mazda 3, Mazda 6, CX-5, and CX-30 models, it features an integrated electronic suction control valve. Typical failure symptoms include long start cranking times, surging idle, and diagnostic code P0087.
HIGH-COMPRESSION GDI MISFIRE & SUCTION VALVE STICKING: Mazda Skyactiv-G engines utilize an ultra-high 13:1 to 14:1 compression ratio, requiring precise 200 bar fuel delivery. When the Denso PE01-13-350 suction control valve sticks from fuel varnish or the internal discharge check valve leaks, low rail pressure causes severe cold-engine hesitation, misfire codes P0300/P0301, and DTC P0087 under highway load.

Pompa alta pressione abbinata (Gruppo circuito carburante)
Funziona sullo stesso circuito ad alta pressione Common Rail. In caso di bassa pressione rail (P0087), verificare la portata della pompa prima di sostituire gli iniettori.
Istruzioni di montaggio
Attrezzatura necessaria: 10mm socket and torque wrench calibrated for 10-30 N·m, 17mm line flare wrench for fuel line pipe nut, Clean engine oil for pump O-ring seal lubrication, Clean lint-free shop cloths and eye protection
- Disconnect negative battery terminal; depressurize fuel system before loosening fittings.
- Loosen high-pressure fuel line union nut slowly to vent residual fuel pressure safely.
- Disconnect electrical wiring connector from SCV spill valve solenoid.
- Disconnect low-pressure fuel supply hose.
- Loosen the two pump flange bolts evenly in half-turn increments to release spring tension.
- Remove pump body; inspect bucket lifter for surface wear or galling.
- Clean cylinder head mating surface and coat new O-ring seal with clean motor oil.
- Rotate engine until driving camshaft lobe is on base circle (lowest lift point).
- Seat pump square into bore; thread mounting bolts finger-tight.
- Torque mounting bolts alternately to 10 N·m plus an additional 90-degree angle turn.
- Hand-thread high-pressure pipe flare nut; torque to 28 N·m.
- Reconnect fuel lines and electrical harness; prime system and check for leaks.
- Angle Torque Specification: Always follow the 10 N·m + 90° specification; undertorquing allows vibration loosening while overtorquing strips aluminum threads.
- Inspect Lifter Surface: Check the bucket lifter contacting the camshaft for scratches; replace lifter if discolored or worn.
- Lubricate O-Ring: Never install the pump dry; lubricate the Viton O-ring with clean engine oil to prevent tearing during installation.
Codici Guasto (DTC) e Protocolli Diagnostici
Codici guasto diagnostici (DTC) comuni generati quando questo iniettore common rail presenta usura, problemi ai circuiti o scostamenti:
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
Injector Circuit Malfunction / Open Circuit
Solenoid coil resistance drift (0.2-0.5 Ω) or piezo stack degradation triggers driver stage shutdown on affected cylinders.
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
Riferimenti incrociati e compatibilità
Codici gemelli, varianti della stessa piattaforma e incompatibilità note.
