Code u0401 - implausible data received from ecm or pcm “the computer”. Means that the ecm is reading wrong data signal from the throttle body back to the computer. It could be throttle body is bad or ecm is going bad. Its better if you can have the mechanic shop check it out. But most likely is the throttle body.
