What does the codes p0442,p0136 &p0141 mean on my 2001 ford taurus it failed inspection for these codes

SOURCE: My taurus failed due to code p0442 ecap emiss ctl sys leak detected (small leak)

Continuous Memory Diagnostic Trouble Code (DTC) P0442 indicates that a fuel vapor leak has been detected [as small as 0.10 cm (0.04 inch)] in the Evaporative Emission (EVAP) system.
Note: Prior to performing the following diagnosis inspect the Canister Vent Solenoid (CV) for contamination. A situation may exist where contamination holds open the Canister Vent (CV) solenoid enough to set DTC P0442 and also plugs the port to atmosphere enough to keep system from being vented quickly.

• After market parts and accessories nonconforming to the EVAP system specifications.
• Damaged, cross threaded or loosely installed fuel filler cap.
• Small holes or cuts in fuel vapor hoses/tubes (EVAP canister tube, EVAP canister outlet tube or EVAP return tube) in the EVAP system.
• Loose fuel vapor hose/tube connections to EVAP system components.
• EVAP system component [EVAP canister purge valve, fuel tank pressure (FTP) sensor, canister vent (CV) solenoid, fuel vapor control valve tube assembly or fuel vapor vent valve assembly] seals leaking.
• CV solenoid partially open when commanded closed.
• EVAP canister leaking.
• Check for presence of fuel filler cap.
• Verify that the CV solenoid is properly seated on the EVAP canister (if possible).
• Visually inspect for cut or loose connections to fuel vapor hoses/tubes in following locations:
  • EVAP canister to EVAP canister purge valve.
  • EVAP canister to fuel vapor vent valve assembly.
  • fuel vapor control valve tube assembly to fuel tank (if applicable).

your code is or the following. Fuel Pump Secondary Circuit Malfunction. This may involve removing your gas tank to fix. Go to the parts store and they can get you the parts you need and let you know for sure.

SOURCE: 2001 ford taurus wont start and anti-theft light is blinking

Either you may be using a key that you had copied from the original or your chip went bad in your original key. Most of cars now a days have the key censor in the key so if it is the incorrect key it will not start your car or if it does not read that chip it will not start

SOURCE: my check engine light came on 2004 ford taurus had

P174 means Oxygen sensor was slow in switching Single, Right or Rear HO2S - Fuel control

P171 means Oxygen sensor not switching - system was at adaptive limits - Single, Right or Rear HO2S - Fuel control

SOURCE: what does this code mean?

P0460 Code - Fuel Level Sensor Circuit Malfunction.

I'm not sure what you mean by you mixed gas, does that mean you switched to a different station or octane level? Does the gas gauge still work fine? As long as it works fine you could keep driving for a few more tanks to see if the problem goes away. If you overfill or run the tank too low it can cause issues with the fuel sender.

When the pump clicks off, you're done filling. Though at 175K miles the fuel sender could just have gone bad. If you start to see symptoms then take it into the shop definitely. About the only thing you could do prior to that is if you're comfortable you could use a digital volt ohm meter (DVOM) and measure the sensor readings at the tank (at the electrical connections).

Good luck.
