On the 1999-2005 Volvo C70, same ETM failure as other P2 platform Volvos. The early C70 (1998-2005, first gen) is most susceptible.

This issue also affects: Volvo S40, Volvo S60, Volvo S70

Common Symptoms

  • Reduced power mode
  • Stalling
  • Check engine light

How to Fix

Confirm ETM failure by scanning for throttle-related DTCs such as P0121, P0221, P2135, or limp-home faults, then use live data to verify erratic throttle angle signals and inspect the ETM connector and wiring before condemning the unit. On 1999-2001 cable-throttle transition and early ME7-equipped C70 models, the usual fix is replacement of the original Magneti Marelli electronic throttle module with the updated Volvo unit or a professionally rebuilt contactless-sensor ETM, followed by software download/adaptation with VIDA/DiCE. Clean the throttle bore only if carbon buildup is minor; cleaning will not repair worn internal position sensors. Typical repair cost is about $700-$1,400 depending on whether a new OEM ETM, rebuilt unit, and dealer software reload are required.
