Parts for your 2020 Volkswagen Amarok-Crank angle sensor

2020 Volkswagen Amarok crank-angle sensor: what it does and when to service it

Based on technical sources, the 2020 Volkswagen Amarok does use a crank-angle sensor (commonly called the crankshaft position sensor, sender G28). The Volkswagen erWin/ELSA workshop manuals for the Amarok V6 TDI list the Engine speed (crankshaft position) sender G28 as part of the engine management. Volkswagen Group Self‑Study Programmes covering the 3.0l V6 TDI (EA897) describe G28 as a primary input for injection and timing control. Diesel management literature from Bosch also details that common-rail systems require a crankshaft speed/position sensor for synchronisation and misfire detection. So yes—this part is relevant and fitted to the 2020 Amarok sold in Australia and New Zealand (V6 TDI), and equally applies to markets where a 2.0 TDI was offered.

On the 2020 Amarok, the crank-angle sensor keeps the V6 TDI’s brain sharp. It reads a toothed wheel on the crankshaft and tells the ECU exactly where the pistons are and how fast they’re spinning. That info is used to fire injectors at the perfect moment, manage start-up, and keep emissions in check. If the signal goes missing or messy, the ute can run rough, stall, or not start at all.

This part isn’t a routine service item, but it’s smart to keep it on the radar. During regular servicing, a quick scan for fault codes, a visual check of the sensor plug and wiring, and making sure the harness isn’t rubbing on the bellhousing or exhaust are worthwhile. Oil contamination or a cracked connector can be enough to upset the signal.

Replacement is straightforward for a trained tech. On the V6 TDI it’s typically mounted low at the rear of the engine near the transmission bellhousing, reading the flywheel’s tone wheel. Access is usually from underneath once the undertray is off. A new O-ring, clean mating face, and correct seating depth are key. Coding is generally not required—clear the codes, check live data for clean RPM signal, and road test. If a no-start persists, confirm power/earth at the connector and inspect the reluctor ring for damage.

• Common symptoms: long cranking, random stalling, no tach needle movement while cranking, limp mode, MIL on.
• Good practice: protect the connector from oil, keep the loom clipped, and use OEM-quality sensors for reliable hot-start performance.

Typical local costs vary with brand and labour time, but budgeting for a quality sensor and about an hour of workshop time is sensible.

FAQs

Where is the crank-angle sensor on a 2020 Amarok?
On the V6 TDI it’s located low at the back of the engine, near the bellhousing, reading the flywheel/reluctor wheel. Access is usually from underneath with the undertray removed. The harness routes along the rear of the block, so checking for chafing there is a good move.

Does a new crank-angle sensor need programming?
Generally, no. The Amarok’s ECU recognises a new sensor without coding. After installation, clear any stored faults, confirm a steady RPM signal in live data, and perform a road test. If issues remain, inspect wiring and the reluctor wheel.

How much does replacement cost in Australia or New Zealand?
Expect parts to sit roughly in the AUD/NZD $120–$300 range depending on brand, with about 0.7–1.2 hours of labour. That typically lands the job around $250–$550 total at most independent workshops. Dealer pricing can be higher.
