2001 Honda Accord - Leak in trunk. I reached under to get my spare out and noticed 4 inches of standing water but no other indication of a leak. I tracked it to about where the wheel well is, near the drain tube to the sun roof. But can't see far enough back to see where it's coming from. It doesn't appear to be the tube. It also appears to be leaking on both sides of the trunk.

Water leaks can be very difficult to find.
You may need to take it to a body shop.
It could be the trunk lid gasket, the rear window seal, or something else.
And you may have mold growing inside.

could be a hose but it is costly
always check the water and have it pressure tested fast
driving with a leak can empty the sustem and burn the engine

P1457 HONDA - Evaporative Emissions Control System Leakage EVAP Canister Systemhttp://engine-codes.com/p1457_honda.htmlForum CodePossible causes- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap There is a Honda factory service bulletin with information on how to diagnose the P1456 on the following Honda models:
1998 Honda Accord
1999 Honda Accord
2000 Honda Accord
1998-2000 Honda Accord
symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vaporsP1457 HONDA Description The evaporative emission (EVAP) control system stores fuel vapor from the fuel tank in the EVAP canister temporarily to prevent it from escaping to the atmosphere and to enable it to be drawn into the engine by intake manifold vacuum and burned. In addition, the onboard refueling vapor recovery system (ORVR) stores fuel vapor generated when refueling in the EVAP canister.

The EVAP control system leak detection method improves the accuracy and frequency of the detection by determining faulty components and vapor leakage for each part. The EVAP control system (from the purge valve to the fuel tank) is divided into two parts. One is the "EVAP Canister Side" (from the EVAP two way valve to the purge valve) and the other is the "Tank Side" (from the EVAP two way valve to the fuel tank). There is 0.04 inch leak detection and 0.02 inch leak detection. If the 0.04 inch leak detection results are OK, the 0.02 inch leak detection runs. The P1457 code is detected when the EVAP system has a very small leak.

P0107 HONDA - Manifold Absolute Pressure Sensor Circuit Low Voltagehttp://engine-codes.com/p0107_honda.htmlForum CodePossible causes- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor poor electrical circuit connector
- Faulty Manifold Absolute Pressure sensor
- Faulty Engine Control Module (ECM) When is the code detected?An excessively low voltage from the sensor is sent to ECMSymptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
P0107 HONDA Description The Manifold Absolute Pressure sensor provides instantaneous manifold pressure information to the engine's Engine Control Module. The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both.


In some vehicles the absolute pressure sensor is built into ECM.

its along way from the trunk to the back seat. check the back window,and the doors, get a water hose and have someone inside check it for a leak. Water in the trunk is usually caused by bad seals at the tail lights. But water in the trunk usually stays in the trunk and spare tire area. If the car has been wrecked, then who knows.

yes there are seams. will require removeing some interior panels but check the sealant between the body panel and the rear inner wheel well bet youy find a leak in that area

buy some foam spray from a can spray it around trunk seam bottom not trunk lid. close trunk to let it dry and shape foam. also check for any holes in trunk. remove all padding to look for wholes. spray foam into any holes found. this foam can also be trimmed after it dries and hardens.

I can tell you why....because it does this in my stratus!!!!

The trunk lid hinges are letting water into your trunk. All the water pools up in and under the spare, the trunk carpet is wet.....more than likely the driver's side of the trunk....pull that trunk carpet back from where that trunk hinge is mounted to the body, reach under there and feel all the water dripping in!

The fix? Unbolt those hinges and put silicone sealant around those bolts and mounts.....that'll take care of that crummy leak.....DODGES!!!!!

can be the rear door seal (check for damage)

or seal around the rear light cluster but that's less likely

Mother nature is too slow in finding leaks. Have someone small get in the trunk with a flashligh and watch as you run a hose over everything. LET THE PERSON OUT!

U need to carefully check the seams of the sheetmetal for any sign of water or dirt from the road, there is no common leak on these cars, in fact they seldom leak anywhere, the water is most likely splash up from the road, unless u left something out like it was sitting when this water accumulated. Let me know that info.
