P0456 Error Code Focus 2002


Drive over to your local Ford dealer parts department; they can verify the part number your looking for- and they can also print out the schematic where it sits on the engine.

P0456 and p0301


The most common misfire causes on the cars I've worked on have been:
  1. Spark plugs
  2. Spark plug wires
  3. Ignition coil
  4. Fuel injector
  5. Wiring to fuel injector
  6. Timing Belt
  7. Vacuum leak or stuck open EGR
  8. Contaminated fuel or bad fuel pump
  9. Weak compression
  10. Blown head gasket

I have a code p0456


P0456 indicates you have a slight leak in the Evap system. I would start by checking the charcoal cannister, duty cycle purge solenoid, and related vacuum hoses.

Engine fault codes: P1684 P0135 P0456


Hi the p1684 means the battery has been disconnected within the last 50 starts, the P0135 is Oxygen O2 Sensor Heater Circuit Malfunction (Bank1, Sensor1), you may have notived an increase in fuel consumption. and the P0456 code means evaporated emissions system -small leak detected the causes could be either A small leak in any of the EVAP hoses or fuel tank hoses, a small leak in the purge valve or vent valve or the EVAP Canister may be leaking
Hope this helps

Dodge neon code p0456


What does that mean? The Powertrain Control Module (PCM) at different times performs various tests on the EVAP system. OBD II Enhanced EVAP systems are in place to keep fuel tank vapors from venting into the atmosphere, and instead purges them into the engine to be burned. Regular pressure tests are conducted by the PCM to monitor the sealed system for leaks. The PCM monitors the EVAP system pressure by watching the fuel tank pressure (FTP) sensor. When the sensor indicates a small leak in the EVAP system, this code is set.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook Potential Symptoms There will likely be no noticeable symptoms other than the Malfunction Indicator Lamp (MIL). This is because the EVAP system is a closed system and only controls fuel tank vapors, not engine management.
Causes Usually this P0456 code is caused by an incorrect or faulty gas cap. Filling the fuel tank2_bing.gif with the engine running could conceivable cause this code as well or if the cap wasn't properly tightened. Any of the following could also be the cause:
  • A small leak in any of the EVAP hoses or fuel2_bing.gif tank hoses
  • A small leak in the purge valve or vent valve
  • The EVAP Canister may be leaking
Possible Solutions First, using a scan tool activate the vent solenoid, sealing the system. Then monitor the fuel tank pressure (FTP) sensor. If the system is sealing properly, the number will stay consistent. If is isn't, the pressure sensor will show that as well. If the system slowly leaks, use a smoke machine and watch for smoke exiting the system at any EVAP component. Any where there is smoke exiting the system, that is the faulty component. Do not pressurize the EVAP system with air pressure. Doing so can damage the purge and vent solenoids in the system.
