Re: TRouble Code 0453, switch high Posted by SWEDECAR [Email] (#112) [Profile/Gallery] (more from SWEDECAR) on Mon, 9 Dec 2013 17:41:52 In Reply to: TRouble Code 0453, switch high, William Hancock, Mon, 9 Dec 2013 12:13:57 Members do not see ads below this line. - Help Keep This Site Online - Signup |
It's an unusual code that points toward the EVAP tank pressure sensor so it comes down to checking for 5V power signal at pin 1 and ground signal at pin 2 at the sensor connector by fuel pump.
To continue fault tracing after that it is best to have a Tech 2 scanner so the correct readings can be obtained from the scan tool.
