    I left the lights on in my car. The car started alright but later that day the check engine light came on. I'm getting error codes p1684 and p0456. Is this related to leaving the lights on?

P0442, P0455 AND P0456 are all evaporative leak monitor test failures (small, medium and large leaks). These codes appear anytime the integrity of the air space above the fuel or the lines to/from the vapor canister or purge valve. If there is no damage to the canister, check the lines that run under the van from the fuel tank and canister to the purge valve (under the hood). Also, check to make sure that the hoses are not split or disconnected where they connect to the purge valve. The P1684 is abit more confusing. This is not a valid DTC for your vehicle. It's possible the scanner the shop you went to is an OTC scanner that is reporting a false code. It's also possible they wrote it down incorrectly. The closest thing that makes any sense is a P1486 which would indicate a pinched hose in the same monitor system as the other 3 codes. Best of luck!

    Follow-up to last posted response, P1684 is a counter for starts. It indicates a battery disconnect within the last 50 starts. Dealers do not use this code because our computers can read the start count information. I called a buddy up north who told me they will not certify a vehicle with this code because too many people will disconnect the battery to clear codes and then bring it in for testing. I know of no way around this other than to drive it for a few weeks and accumulate the required 50 key cycles.

Yes, the P1684 on the Chrysler line does not indicate a fault. My sebring had codes p0442 and p0456 both indicating very small evep leaks. When I did the 3 time switch on of the ignition, the odometer readout gave me the p1684 first and then the other two. The scanner at the garage only indicated two "very small evap leaks" one for the second two codes. Clearly the first is a status indicator such as recent battery disconnect or another non problematic indicator. Wouldn't it be great if these manufacturers at least gave you the information to identify what their dummy lights are telling you so you didn't have to go on faith at the garage?

Check engine light comes on


yes. the rubber gaskets do wear out. on most vehicles the gas cap
should be tightened 'til it"clicks". you probably can't tell from the
"appearance" but if you tighten 'til it clicks then drive for awshile and still
get the same code, the next step is a NEW gas cap/

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

What are troubleshooting codes P1684 and P0456?


P0456 is a small vacuum leak - see if you can trace down the vac lines for inspection according to the diagram that's on the sticker under the hood (it should be near the end of the hood prop on the covering over the radiator). I just took a picture of my 2002 Chrysler Town & Country but to get it small enough to upload you can't read the detail.

P1684 is an easily trigerred code that is from a diagnostic reader or battery issue - not 100% sure of it's cause but it does not trip the engine light.

What is the diagnostic codes P 0700 P1684 p0442 p0455 p0456 on a 2001 dodge Caravan with a 3 3"


P0700: EATX Controller DTC present
P1684: Battery was desconnected
P0442: EVAP leak monitor medium (.040). Leak detected.
P0455:
EVAP leak monitor large. Leak detected.
P0456: EVAP leak monitor small (.020). Leak detected.

I suggest check the lines and flow it down to the ldp (leak detection pump) that is just behind the steering gear under the van It has a wire connector and 2 large EVAP hoses. look for any split or crack then follow the lines back to the tank. Even a small crack is a leak.

Hope helped with this. Remember rated this help. Good luck.
