Hey Scotty i have a 2012 toyota tundra i bought at a dealer for 14k with 175,000 miles. Just recently my check engine light came on and had a friend scan it and the code p1604 replaced throttle body. It said "startability malfunction" and that the throttle position sensor parameter was erratic. Please help
For future reference please take a moment to note the difference between the title of your post and the body. The former is intended as a short description, is length-limited (long entries are cut short), and is not for all the details of your issue. That belongs in the body of your post. Thank you. (Title edited.)
If the engine starts just fine, I would not worry about it. First make sure the battery and alternator are up to par. Clear the code. If it came back, then check the freeze frame data.
