Having problems filling the fuel tank on my 2001 hyundai elantra. Any solutions?


Common code you have there. My 2001 Elantra has kicked at least one if not both several times. The simplest trick is to get the cap tighter. Turn it till it clicks, then lean into it and see if you can get a few extra clicks. Ever since I've done this I haven't gotten these codes. Once you've done that, you can remove the battery cable for 30 minutes and then reinstall. The check engine light should be off then, but of course now you'll have to reset your clock and radio. This car is getting older, so it could very well be that something much larger is going wrong, so good luck and here's hoping!

P0450
- Faulty Evaporative Emission System (EVAP) Pressure Sensor
- Evaporative Emission System (EVAP) Pressure sensor harness is open or shorted
- Evaporative Emission System (EVAP) Pressure sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)

P0446
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Vent control valve harness is open or shorted
- Vent control valve circuit poor electrical connection
- Faulty vent control valve

Engine Check light


Take it to autozone or another place like it and have them read the codes and tell us what they are.

What should I do to get my 87 ford econline straight 6 ready for a smog?


Before the emission test make sure your air filter is clean, change the oil, and make sure your engine is in tune. Worn spark plugs are the #1 emission item that will usually fail the car. Make sure the check engine light works properly. To check the light, turn on the ignition, the light should come on for a second or two and then go off. After the engine has started the light should remain off. If your light is on they will fail the car.

Emission Failed Inspection. Engine light not on.


I've always found the following to help with emissions tests on older cars: Check & replace air cleaner if dirty (difficult to see light through it), Check spark plugs ( will also be good indicator of any bad cylinder so keep them in order of removal) - if any look/measure bad, replace the set. Check engine oil quality & replace if dirty (or you can't remember the last  time it was changed). Dirty oil = higher emissions.
Run engine on higher grade fuel for a few days and during test (better fuel = lower emissions). If o2 sensor is the problem it will set off codes.

Mazda rx8 fault code p0410 secondary air system we have a mazda rx8 2006 model, p0410 fualt code has come up, want should we looking to check, test and poss change?


The P0410 code refers to the (secondary air system) emissions system. The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.
.
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.

A code P0410 may mean that one or more of the following has happened:
  • Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
  • Blown AIR pump fuse due to freezing up
Possible solution:
This may be covered under the emissions warranty on the vehicle. If your vehicle is out of bumper-to-bumper warranty, check if the emissions warranty is still valid!
  • Replace the AIR pump AND one-way check valve
  • Test and clean the AIR pump AND test and replace the one-way air check valve
  • Replace the AIR pump inlet hose
  • Replace the AIR pump fuse (found under the hood)
It is really only an emissions issue and won't harm your car's engine ot drivetrain. It will however mean you won't pass emission testing if you live somewhere that tests for that like I do!

Heater


You did not say what engine you have. I will assume it is the 3.5 liter 24-valve engine.  This is most likely due to air in your cooling system. The only way to eliminate the air lock is to vent it out at the thermostat housing.  If there is air in the system, the engine will overheat and also fail to send heat to the heater.  When the engine is running at high RPMs the problem is mitigated, but it is trapped air that is probably the culprit.
