Parts for your 2022 Ford Transit-Knock sensor

2022 Ford Transit knock sensor: is it actually there?

Short answer: for most 2022 Ford Transit vans sold in Australia and New Zealand, a conventional knock sensor isn’t fitted. The local model runs the 2.0‑litre EcoBlue diesel, and Ford’s own technical literature confirms there’s no knock sensor shown in the diesel engine’s component locations or serviced parts. The Ford Workshop Manual for the 2.0L EcoBlue, the Electronic Parts Catalogue for AU/NZ Transits, and the diesel Powertrain Control/Emissions Diagnosis manuals (which don’t list knock-sensor DTCs like P0325–P0334) all point the same way.

Why’s that the case? Knock sensors are primarily a petrol-engine tool. They listen for detonation so the ECU can trim ignition timing and protect the engine. Diesel combustion is different: it’s compression-ignited and managed by very precise multi-stage injection. On the EcoBlue, the ECU controls combustion using fuel pressure, injector timing, boost control, and feedback from sensors such as the crankshaft position, MAP/MAF, EGT and NOx. “Diesel knock” is largely characteristic combustion noise, so a traditional knock sensor isn’t especially useful to manage it.

There’s a wrinkle though: some 2022 Transits in other markets use petrol V6 engines (3.5L Ti‑VCT PFDi and 3.5L EcoBoost). Those variants do run knock sensors—typically two, bolted to the block—to monitor combustion noise and adjust spark timing under load. Ford’s Workshop Manual and Parts Catalogue list these sensors and the associated fault codes for those engines.

If someone’s got a 2022 Transit imported with a petrol V6 and they’re chasing knock-sensor concerns, a few clues help. Common signs include a check engine light with codes in the P0325–P0334 range, audible pinging under load, soft performance from timing being pulled, or poor fuel economy. Before rushing to replace the sensor, rule out the basics: wrong-octane fuel, intake or vacuum leaks, carbon build-up, and dodgy engine mounts that can mimic “knock” with extra vibration.

• On petrol V6 Transits, knock sensors are usually mounted on the engine block (often beneath the intake). They need clean mating surfaces and correct torque to read block vibration accurately.
• Always inspect the harness and connectors for oil or coolant contamination, abrasions, and poor pin tension.
• Use scan data to confirm both the fault code and live knock retard behaviour before and after repairs.

For AU/NZ diesel 2022 Transits, there’s nothing to service or replace in this area because a knock sensor isn’t part of the package. Focus routine maintenance on clean air and fuel delivery, correct oil spec, DPF/SCR health, and up-to-date ECU calibrations—the things that keep EcoBlue combustion tidy and efficient.

FAQs

Does the 2022 Ford Transit in Australia or New Zealand have a knock sensor?
No—on the locally delivered 2.0L EcoBlue diesel it isn’t fitted. Ford’s Workshop Manual and Parts Catalogue for AU/NZ Transits don’t list a knock sensor for the diesel, and the diesel diagnostic manual doesn’t include knock-sensor codes either. Petrol V6 Transits in other markets do have them.

Where would a knock sensor be on a 2022 petrol Transit?
On the 3.5L Ti‑VCT PFDi or 3.5L EcoBoost V6, there are typically two knock sensors bolted to the engine block, often under the intake area. Access usually involves intake components off, then removing and refitting the sensors to the specified torque so they can “hear” the block correctly.

How does the diesel EcoBlue control combustion without a knock sensor?
The ECU manages combustion using injection timing and pressure, turbo boost, and feedback from sensors like the crankshaft position, MAP/MAF, EGT and NOx. It tracks combustion quality via these signals rather than listening for petrol-style detonation, so a traditional knock sensor isn’t required.
