Lexus RX engine mount issue

My 2014 Lexus RX with a gasoline engine is showing a defective engine mount. Symptoms are an error stored in the error memory and uneven idling. Suspect cause is a defective cable or plug connection. Anyone else seen this?

A 2014 Lexus RX is experiencing a defective engine mount, indicated by an error code and uneven idling. The suspected cause is a faulty cable or plug connection. Minimal vibrations and no visible cracks suggest the issue might be electrical rather than mechanical. A similar case revealed a partially disconnected wire to the mount sensor, and the problem was resolved by addressing the plug connection, confirming the initial suspicion.

Engine mount, huh? I had something similar with my RX. Uneven idling can be a real pain. Did you check for any unusual vibrations? Could be related to the transmission mount as well. Is the rubber mount showing any obvious signs of wear or cracking?

Vibrations are minimal, but present. Cracks aren't visible. Could a bad plug really cause the error code?

Yeah, a faulty connection can definitely throw off the sensor readings and trigger the error. Given it's idling rough and you've got that error, I'd say it's worth getting it checked professionally. My issue turned out to be a partially disconnected wire to the mount sensor.

Thanks. The plug was indeed the culprit. Repair cost was 95€. Appreciate the help.
