automotive scan tool<\/a>, you will want one to try and figure out what’s going on with a code P0453. That’s because the best way to figure out what’s going on is to connect a scan tool and look at the fuel tank pressure readings.<\/p>\nYou can then use the data to determine if the sensor is giving accurate readings or if there’s a problem somewhere else. Even without a scan tool, you can check for power at the fuel tank pressure sensor.<\/p>\n
It should have a 5-volt reference signal and a good return signal back to the PCM. Always check to ensure there’s a good ground in the system too when you’re looking at the wiring system on sensors.<\/p>\n
You should also visually inspect the fuel tank for damage. While this is a rare cause of a code P0453, a damaged fuel tank can throw the code.<\/p>\n
If you don’t pick up a fuel smell and all the measurements come back normal, the problem might be with the PCM, but this is extremely rare.<\/p>\n
You can also try swapping out the carbon canister and carbon canister vent valve, but typically problems with these components will show up when you’re looking at the readings from the fuel tank pressure sensor.<\/p>\n","protected":false},"excerpt":{"rendered":"
The last thing you want to see when you start up your engine is a check engine light. But what’s even worse is seeing that check engine light and having no idea what it means or how to fix it. … Read more<\/a><\/p>\n","protected":false},"author":1009,"featured_media":509006,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"no","_lmt_disable":"no"},"categories":[320],"tags":[100363],"modified_by":"Mark Stevens","_links":{"self":[{"href":"https:\/\/cartreatments.com\/wp-json\/wp\/v2\/posts\/510459"}],"collection":[{"href":"https:\/\/cartreatments.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cartreatments.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cartreatments.com\/wp-json\/wp\/v2\/users\/1009"}],"replies":[{"embeddable":true,"href":"https:\/\/cartreatments.com\/wp-json\/wp\/v2\/comments?post=510459"}],"version-history":[{"count":0,"href":"https:\/\/cartreatments.com\/wp-json\/wp\/v2\/posts\/510459\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cartreatments.com\/wp-json\/wp\/v2\/media\/509006"}],"wp:attachment":[{"href":"https:\/\/cartreatments.com\/wp-json\/wp\/v2\/media?parent=510459"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cartreatments.com\/wp-json\/wp\/v2\/categories?post=510459"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cartreatments.com\/wp-json\/wp\/v2\/tags?post=510459"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
