Parts for your 2021 Volvo Xc60-Camshaft sensor

2021 Volvo XC60 camshaft sensor — what it does and when it needs attention

Based on Volvo technical documentation and parts catalogues, the 2021 Volvo XC60 is fitted with camshaft position sensor(s). Volvo VIDA (MY2021 SPA platform, VEA 2.0‑litre engines) lists Camshaft Position (CMP) sensors as components 7/193 and 7/194 monitored by the Bosch MED/MG1 engine control module. Factory wiring diagrams and the OEM parts listings for the 2021 XC60 ranges — T5, T6, T8 Recharge and the B5/B6 mild‑hybrids — show at least one Hall‑effect camshaft sensor, and most variants use two (one on the intake cam and one on the exhaust cam). So yes, it’s absolutely relevant on this model.

On the 2021 XC60, the camshaft sensor feeds the ECU precise information about where the cam(s) are in their rotation. That matters for quick starts, smooth idle, proper timing of sequential fuel injection, spark timing, and the control of variable valve timing. The sensor’s clean signal lets the ECU phase the cam(s) to suit load and revs, which is how the car delivers good grunt without burning extra fuel. Lose that signal and the ECU falls back to safe settings, which can dull performance and bump up consumption.

There’s no scheduled maintenance for a camshaft sensor, but it lives under the bonnet in heat and oil vapour, so age, contamination, or a tired connector can cause dramas. Telltales include hard starting, lumpy idle, hesitation on take‑off, random stalling, higher fuel use, and a dash message like “Engine System Service Required.” Common fault codes include P0340–P0345 variants. Before condemning the sensor, a good tech will check wiring, connector pins, and oil intrusion, as those are frequent culprits.

Replacement is straightforward with the right steps: disconnect the battery, pop off the engine cover, unplug the sensor, remove its retaining bolt, then ease the sensor out of the cam cover. The new unit’s O‑ring should be lightly oiled before refitting. After installation, clearing fault codes and performing any required VVT/cam relearn with a capable scan tool is wise. Sticking with genuine or high‑quality OEM‑equivalent parts keeps the signal clean and reliable. Because VVT control depends on healthy engine oil, regular oil changes using the correct Volvo‑spec oil are the best preventative maintenance for both the cam sensor signal and the cam phasers.

• Typical location: at the cylinder head by the cam cover, many 2021 XC60 variants have one sensor per cam.
• If intermittent: inspect the harness routing, connectors, and seals for heat or oil damage before replacing the sensor itself.

Popular questions about 2021 Volvo XC60 camshaft sensors

Does the 2021 XC60 have one or two camshaft sensors?
Most 2.0‑litre petrol and hybrid variants in 2021 use two — one for the intake cam and one for the exhaust cam — to give the ECU precise control of dual VVT. Some market configurations may list a single CMP in parts catalogues, but VIDA wiring and engine management for the VEA engines typically support two.

Can it be driven with a failing camshaft sensor?
It’ll usually run, but not happily. The ECU will default to safe timing, so expect sluggish response, rough idle, and higher fuel use. Prolonged driving like this isn’t ideal for the catalytic converter or turbo. It’s best to get it scanned and sorted promptly.

What’s the usual fix if a code like P0340 shows up?
A proper diagnosis comes first: check the connector for oil, the loom for chafe, battery voltage/grounds, and then the sensor itself. If the sensor is out of spec or contaminated, replacement is the go. After that, clear codes and confirm with a road test, a cam/crank correlation or VVT relearn may be needed.
