Cracking the P0120 Case on Your 2022 Volvo S60
Your 2022 S60 — Volvo's sporty sedan — just lost its composure. The check engine light is on, power is reduced, and P0120 identifies the culprit: a throttle position sensor circuit malfunction. The S60 shares the SPA platform and 2.0L four-cylinder powertrain with the XC60 and XC90, available as T5 (turbo, 247 hp), T6 (turbo+supercharged, 316 hp), or T8 Polestar Engineered (455 hp combined). All variants use the same electronic throttle body with integrated TPS.
Symptoms
- Check engine light illuminated
- "Reduced Engine Performance" warning
- Significant power loss — especially noticeable in the sport sedan context
- Throttle response delayed or erratic
- Rough idle or stalling
- Polestar performance mode may deactivate
Ranked Suspects
1. Throttle Body Failure
The electronic throttle body on Volvo's 2.0L engine can develop internal wear. The TPS potentiometer or motor degrades, producing out-of-range voltage signals. This is the same throttle body used across all SPA platform Volvos.
2. Carbon Deposits
The direct-injection 2.0L engine generates crankcase vapors that coat the throttle bore. T6 and T8 models with superchargers are particularly prone to carbon accumulation in the intake system.
3. Wiring Heat Damage
The S60's engine bay packs turbo (and possibly supercharger) hardware alongside the throttle body. Heat cycling can degrade TPS wiring insulation over time.
4. ECM Calibration
Volvo releases ECM updates through VIDA. A calibration for throttle adaptation may be available for the 2022 model year.
5. Pedal Position Sensor
The dual APP sensor pedal module can develop wear at common throttle positions, especially in a sport sedan that's driven more aggressively than SUV counterparts.
Investigation Steps
- Scan with VIDA or OBD-II scanner for codes and freeze frame
- Inspect throttle body connector and bore
- Monitor live TPS voltage during controlled sweep
- Check for Volvo TJ updates on SPA throttle system
- Test APP sensor correlation
Cost Breakdown
- Throttle body replacement (Volvo OEM): $400–$850
- Throttle body cleaning: $175–$375
- Wiring repair: $150–$400
- ECM software update: $150–$275
- Pedal module: $175–$400
Can I Drive With P0120?
Only at low speed to a shop. The S60 in reduced-power mode loses its sport sedan character entirely. Check whether your 2022 S60 is within Volvo's 4-year/50,000-mile warranty.
DIY vs Professional
Warranty first. Out of warranty, the S60 shares its entire powertrain with the XC60/XC90, so repair procedures and parts are identical. Throttle body cleaning is a solid DIY first step. Full replacement requires VIDA.
Frequently Asked Questions
Does the S60 share the throttle body with the XC60/XC90?
Yes. All SPA platform Volvos use the same 2.0L engine family and electronic throttle body. Repair procedures are identical.
Is the T8 Polestar Engineered affected differently?
The T8 Polestar Engineered uses the same combustion engine and throttle body as other T8 models. The electric motor can provide some power even with a throttle fault, but reduced-power mode still activates for safety.
Is the S60 Recharge affected?
The S60 T8 Recharge (plug-in hybrid) has both an engine and electric motor. P0120 affects the engine throttle body. The electric motor may provide some mobility even with the fault, but the system will enter reduced-power mode.
Can I prevent P0120?
Periodic throttle body cleaning (every 30,000–40,000 miles) helps prevent carbon-related P0120. Using quality fuel and keeping up with oil changes also reduces crankcase vapor contamination.
