Jeep Cherokee Error Code P0456

Emissions System - Small leak detected 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 p0456 jeep liberty them into the engine to be burned. Regular pressure tests are conducted by the PCM to p0456 jeep wrangler jk monitor the sealed system for leaks. The PCM monitors the EVAP system pressure by watching the fuel tank pressure (FTP) sensor. When the sensor po456 code indicates a small leak in the EVAP system, this code is set. 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 tank 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 fuel tank hoses A small leak in the purge valve or vent valve The EVAP p0457 code 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.

Have a look behind the LH rear wheel cover, there you will find the EVAP canister and several hoses. maybe one hose is in bad shape or loose. The line runs from there to the purge solenoid in the engine bay, so there are many places where a line can be shaved through. __________________ __________________ Frank JEEP Grand Cherokee 4.7 Lmtd 2004 HID 8000K in low and fog / Quad Squad member KYB Gas-a-Just shocks / Pirelli Scorpion ATR 245/65/17 - Transgo reprogramming shiftkit.

The dealer "advised" they couldn't find anything wrong ( tank-less gas cap helping eliminate that issue... ) -- They tried to smoke it but "advised" they couldn't find anything so it was just cleared. Well, it's been about 4 weeks and its back! Nothing has changed and I've driven it maybe 200 miles since it was cleared and checked last at the reputable dealer. Anyone have any ideas? Anywhere I can personally look for something?, Needing the great people in this forums help and advice, please. Any new TSB's out for our SRT's firmware,etc.?

I have what appears to be the exact same issue. I have a 2014 GC SRT, and about 1800 miles on it. The MIL came on, P0456 is the error, and the dealership says they see nothing wrong. Cleared, and came back on 2 days later. I'm frustrated, and reading all of the posts to see if anything helps. Sooner or later, someone will have to discover something, but as of right now, I don't see a simple solution to this annoying issue. __________________ #3 03-25-2014, 02:27 PM Artofnoize Member My Jeep: 2014 6.4L SRT8 WK2 Join Date: Mar 2013 Location: Toledo, Ohio Posts: 521 Thanks: 11 Thanked 27 Times in 27 Posts Rep Power: 2029 I want to say there is a flash for this issue. #4 03-25-2014, 05:42 PM 2014_SRT_Steel Member My Jeep: 2014 6.4L SRT8 WK2 Join Date: Oct 2013 Locati
