Check Engine Codes

Dummy light came on, still running like a top though. 2007 V6 TRD

Pulled the Code P0452 - Emissions System Pressure, what's this about...Fuel Tank Pressure Sensor is my best guess.

Stored Codes PO100, P0102 and P0103 all Airflow related ??

and a P0300 random misfire...likely time to change the plugs.

 

The pcm uses the fuel tank pressure sensor for information when performing various evap system functions, like purging and leak checking.

The p0100/102/103 codes are MAF sensor related, like it thinks the connector is unplugged.

P0300 means the pcm knows it has a misfire, it just cant pin down which specific cylinder.

 

So the fuel tank pressure sensor code and the P0100/102/103 codes are directly related/linked to the same issue?

 

Probaby not related.. unless those circuits share a common fuse that blew.

I assume I am looking for the part on page 3 here http://www.customtacos.com/tech.old...6toyrm/06toypdf/06rmsrc/rm2006ta/01200110.pdf
Does anyone have a RockAuto link to the part?

 

I like to update when I finally get nagging issues squared away. Also, see the related post, https://www.tacomaworld.com/threads/ghost-in-the-machine.639805/ and here https://www.tacomaworld.com/threads/evap-check-engine-codes.636808/#post-21931473
Through some trial and error, I was able to track down the ABS and Brake light issue, which wasn't another faulty wheel speed sensor as suspected. It was was actually a worn wire (in about the middle of the cab under the truck) that had chafed and lost connection. While I was in there I found more than one suspect wire, repaired (NASA wire splice technique). The check engine code went away too! I have run about 600 miles and it has not returned. Oh, and I change all 6 plugs awhile back.
