The fueltankpressure sensor is located on the top of the fuel tank on the fuel pump sending unit
What do you do to test this part or should I just replace it now so the ck. eng. lite goes out to be able to get this truck to pass smog in Ca.
yoy wouldneed a scanner with live data to watch readings....The sensor is 50 dollars or so and easy to replace. They do fail
Is it possible that the fuel cap is the problem? another person said that is the problem.
no it would not be its genarally the sensor
How long will it be in miles or drive cycles till the ck. eng. goes off so I can smog the truck in California.
the engine light will not go untill the problem is repaired or thelight is shut offit should be quick if you follow the drive cycle
A complete driving cycle will perform diagnostics on all monitored systems and can usually be completed in less than fifteen minutes.

The truck is not registered, on non op status can I clear out the code with an OBD II .
yesu can...but the readiness monitors will not set untill a drive cycle is performed
