2000 Honda Accord Problems
RepairPal has identified the most common problems with the 2000 Honda Accord based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The Honda Accord has a known issue with engine oil leaking from the ignition distributor shaft seal.
Leakage from the shaft seal coats the electrical components of the distributor with engine oil causing:
Cleaning the distributor cap and rotor can help or resolve driveability issues temporarily, but the mentioned issues will return shortly.
Once this issue is diagnosed, the ignition distributor shaft seal must be replaced, and the distributor shaft bearing must be inspected.
Some models have shift quality problems when shifting into third gear. A new "third gear set" from Honda will address this issue.
The 1990-2016 Honda Accord engine oil pressure sensor may leak from normal operation.
More information about the oil pressure sensor here.
To correct the leak, the sensor must be inspected, properly sealed and installed, or replaced with new.
The front axles are prone to failure on the 1990-2002 Honda Accord 4-Cylinder. This will be evident as fast clicking or popping sounds will be audible while driving, most commonly when the steering wheel is turned while the vehicle is in forward motion.
Constant velocity (CV) axles, sometimes called a “half-shaft”, are designed to allow the wheels to be driven by the transmission, even when turning the steering wheel.
They are manufactured of a shaft with a gear at both ends. When one of the gears on the end of the shaft fails, it will make noise as the vehicle is driven.
The Honda Accord may have issues with the idle air control system, causing:
- Erratic/bouncing idle
- Poor fuel mileage
- Illumination of the check engine light
- OBD trouble code P0505
- Engine stalling is possible
The idle air bypass system is made up of vacuum lines, an idle air control valve (IACV), the throttle body, and intake manifold, and allows enough air into the engine to idle when the throttle body is closed. The OBD trouble code P0505 refers you to this system to inspect for failures.
The most likely cause is a dirty or failed IACV, but vacuum lines, intake manifold gasket, throttle body gasket, and IACV gasket should be inspected.
In all cases involving the IACV, the throttle body ports should be cleaned prior to installing the IACV onto the throttle body.
Smelling burning engine oil is common on the 1990-2002 Honda Accord 4-cylinder engine, and is associated with oil leaking from the valve cover. It is most common to smell the oil burning at a stop light, or just after you shut off your engine.
Engine oil leaks from the valve cover, drains down, and settles on the exhaust manifold, which burns the oil upon contact due to high exhaust gas temperatures. This creates an odor that comes through the vents, and can be smelled around the front of the vehicle.
Valve cover gasket replacement will correct both the leak and the smell of burned oil at the same time. If the ignition coil or spark plug wire was soaked in oil, it will need to be cleaned or replaced to stop or prevent misfires.
This seal wraps around the camshaft to prevent engine oil from leaking where the camshaft exits the cylinder head.
The exhaust recirculation valve (EGR) on the 1990-2007 Honda Accord V6 may fail, causing:
The EGR valve has open and closed positions, and opens or closes on command from the computer.
Exhaust gases constantly pass through the valve when it is open, leaving carbon deposits on the valve. These carbon deposits may lead the the valve sticking in the open or closed position.
To correct this issue, sometimes it is sufficient to clean the valve, but replacement is recommended in all cases.

The Honda Accord is known for premature alternator bearing failure. The alternator shaft bearing alerts of mechanical failure by making a howling or grinding noise, but other symptoms may appear, including:
The correction is to replace the alternator immediately.
Four cylinder models of the Honda Accord from 1990-2001 have a known issue with ignition distributor shaft bearing failure, which causes:
The ignition system uses the distributor to send high voltage electricity to the spark plugs at the right time. It accomplishes this timing mechanically by a shaft, which connects the crankshaft and ignition distributor, so they spin at the same rate. That shaft, part of the distributor, rests in a bearing inside the distributor.This bearing, the distributor shaft bearing, is known for failing, and allowing the shaft to move slightly.
As the bearing fails, it allows the shaft to move away from the shaft seal, and oil pours into the distributor cap, causing misfires.
The play in the shaft can also cause contact with the crankshaft position sensor, causing a no start problem.
Total bearing failure will be most evident from the grinding noise that changes with engine speed, and oil in the ignition distributor cap.
If the bearing is making noise, driving or running the vehicle can result in catastrophic engine failure.
To correct this issue, the ignition distributor and shaft must be replaced. Any damage to the crankshaft position sensor will necessitate replacement as well.
One or both of the rear sway bar end links may break resulting in a knocking noise from the rear of the vehicle.
A faulty brake master cylinder reservoir filter can cause the brake system indicator to illuminate after a cold start and then go off. Replacement of the reservoir filter will commonly fix this problem.
