2004 UK Prius 138,000 miles Driving along today and got the red triangle. Codes read by breakdown guy was Misfire but he couldn't connect to see what cylinder. He cleared codes and off went... Now the light came on again... Have read code using techstream. P0340 P0A90-239 Any reason for the codes being different? Thank you for any help Posted via the PriusChat mobile app.
I've no idea what the reader was, small gray and red. Small screen handheld device. Codes were P0301, p0302, p0303, p0304 Car was still running fine when he checked. No noticeable misfire at the time. Posted via the PriusChat mobile app.
stick with tech stream, and search online for the service manual. it will have code meanings and trouble shooting

Codes were cleared and today I've just had the red triangle Code P0343-601 Why does it keep throwing different codes? Posted via the PriusChat mobile app.
Am having new spark plugs fitted tomorrow, don't know if that'll have any impact. Posted via the PriusChat mobile app.
P0A90/239 is the latest code to appear. All other codes have been cleared. Posted via the PriusChat mobile app.
