2002 S60 Idle jumping, no power, P2172 code

Hello.

I have just completed some repairs to get car to start. New A/C pulley, serpentine and Plugs. There was also a new Crank Position Sensor put in.

Car started up fine, idled well, A/C came on and cycled fine, so I took it out for a drive. Less than a mile later at a stop sign, idle starts dancing and the is basically no response from the throttle pedal.

Code check produced P1610 and P2172.

Can I have some suggestions as to where to begin? Prior to this there were no reported issues of rough running or loss of power, and believe me, my daughter would have been all over me about it!

Thanks

That's ETM failure. Your S60 is a non turbo I'm guessing. It is the last year for the dreaded MM electronic throttle body.

How many miles are on it? Is the ETB white label or yellow label

ETM part number 36050564 is specific to your year and model and SHOULD come pre-programmed with some software however whether software will be correct for your car depends on your ECM (engine control module) software numbers.

Those codes point to an internal failure of the ETM. Do remove the rubber hose going to the ETM and check the butterfly valve operation by hand. If it's binding try to clean it, otherwise turf it.

Don't bother with a contactless Sacer kit.
