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: Ford Explorer, Ford Transit, Ford Transit Connect

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.

Common Symptoms

Squealing from timing cover
Belt shows cracks
Engine won't start after high mileage
Ticking noise from front of engine
