p0442 code keeps coming back on my 03 renegade (70 000kms). I took it to a mech the other day he ran tests, everything came out good...cleared the code...now its back on again. Before I take it back to get a smoke test done...is there anything I could do at home ( i don't have jack or anything to lift it)?. Also how long roughly would it take a mech to do a smoke test?...my mech charges $85/hour cdn so I'm trying to get a rough estimate. Also if this helps on my computer up top it said for the last 2 months I've had it i get roughly 16.9 L/100km now its slowly dropped to 16.2L/100km. Any help would be great. I'm kinda cashed strapped for the next bit...so I hope that this little leak won't cost an arm and a leg. |

Besides looking at the rubber evap lines on the canister(by gas tank) you need a smoke test done.They should charge a flat rate diagnostic charge for a diag,usually between $80-$150 for the diag which would include a smoke test for EVAP codes. |

If it helps (i'm a noob) I noticed when I unscrew the gas cap it doesn't release or make the sound of pressure releasing. It use to before the p0442 code came up |

It use to before the p0442 code came up This is because the gasoline vapors are not being contained any longer, thus the p0442 which is an evaporative emissions leak. A smoke test is the only accurate way to diagnose the leak. If your lucky you will only need a gas cap. |
