02 V70 - Codes related to ETM?

02 V70 NA
142k, Original ETM

Plugs and coils have all been replaced in the last 10k. MAF was cleaned about 10k ago. I've had zero issues since I've owned it starting at 132k.

My son tried to start the car today, it sputtered and would not rev. The yellow triangle came on, along with 'Service Engine Soon' (not the maintenance reminder). He let it rest for 5 min, at which point it started fine and he drove it home. I pulled two codes:

P2172: Throttle Actuator Control System - Sudden High Air Flow Detected
P1610: Ignition Discharge Module (IDM) Group D

The first one seems ETM related, but I'm not sure if that's a red herring.

Is this an ETM problem?

Thanks.
