09 crf450 blink code
« on: January 28, 2012, 09:30:28 AM »
Just put a top end in and got a blink code of 8 when I started it. Is that TPS? What can I do to reset/fix?

8-1 is low voltage of the TPS, 8-2 is high voltage.

If you just did a top end, Id assume the connector got dirty when you took it apart. Pull the plug and clean it, plug it back in, see what you get.

the big connector on top of the air box? I tried the lower one but I'll give that a try.

plug is clean, still does it. could there be an issue with the sensor on the cylinder?

No, the TPS sensor is on the throttle body.
