I love this car, has performed superbly since I bought it with 14,000 miles on it. A few days ago I left it outside my heated garage (I was working on a project inside the garage and there was no room for the cars) and it got quite cold, low 20's, high teens, and also snowed a few inches. Yesterday I finished my project in the garage and started the Toyota up and it was running kind of rough and threw the ol' check engine idiot light. I pulled it into the garage and let it warm up for a couple of days. This morning I started it up and it started and idled just fine. No check engine light. I hooked up my BlueDriver scanner, did a deep scan and got 4 pending trouble codes, P0304 cylinder 4 misfire, P1421 Solar sensor circuit (Passenger), P1424 Solar sensor circuit (Driver), and P1604 startability malfunction. I think I will go ahead and erase all codes and hope this is just due to transient connector problems. Has anyone else experienced similar issues?
many people report problems or codes appearing as the weather starts to really cool down. Alomost always when the engine warms up those problems no longer appear but could repeat themselves the next day ot days if the same or worse conditions repeat themselves. it is best to ignore it as it is just a non-fatal error or event.
