00-30-001 2000 ACCENT DMTL DIAGNOSIS: DTC CODES P1401, P1402 AND P1403

p1402 - dm-tl air pump motor is shorted or disconnected.

2000 model year accent is equipped with a new enhanced evaporative emission system. this new system is capable of measuring leaks as small as 0.020" diameter. the new system pressurizesthe evaporative emission system with a diagnostic module for tank leakage (dm-tl), while the previous model's system appliedengine vacuum through the purge valve to detect system leaks.

service information
vehicles that have the check engine light illuminated and have dtc p1401, p1402 and p1403 stored in the ecm should have their electrical systems diagnosed related to the appropriate dtc. these codes are not related in any way to an evaporative emission system leak. the conditions that set the diagnostic codes areas follows:
p1401 - dm-tl air pump motor current draw is higher or lower than expected (normal = 17-36 ma).
p1402 - dm-tl air pump motor is shorted or disconnected.
p1403 - dm-tl changeover valve is shorted or disconnected

hiya if the rear lights are remaining on ? with no ignition it will be the brake lights staying on this is easily remendied/ checked by trypulling the brake pedal up by hand and see if lights go off ? if so then you will need to adjust the b/light switch which is positioned adjacent to pedal and can be screwed inwards towards the pedal untill the plunger on switch is pushed into the switch which puts lights off ensure pedal is fully up then adjust switch reconnect the wire/plug and press pedal slightly to ensure b/lights operate ok and then go off with pedal released ? on hyundai the brakelights do not req ignition on to operate hence more likely problem is as above good luck

Yep Ron... go to http://www.hmaservice.com/ anb register (veh VIN). Afterward, you can navigate the site to find the information you seek (service bulletins, manuals, wiring diagrams, etc.).

The fuel filter on a 2005 Hyundai Accent depending on where it was manufactured and when, is possibly external and on the outside of the fuel tank directly above the fuel pump and accessible by removing the back seat. Or it is actually inside the fuel tank and requires removing the back seat, the metal panel, the fuel pump itself and then accessing the filter. Your vin. no. can determine which model you have and of course how much work you'll have to do

You need to check two things.

First, there is a heat shield on top of the front of the motor where the o2 sensor you already replaced is. It's got (4) 12mm bolts. Remove it and check the exhaust manifold (big thing you put the o2 sensor into) for cracks. If there are any cracks, you'll get o2 sensor codes. Replace the manifold.

Second, if the manifold is fine start the car and listen to the exhaust pipe under the engine for leaks. Or if you already know the exhaust is loud... that's gonna do it too. A leaking exhaust pipe on an Accent will set secondary o2 sensor codes.

SHOULD you try to change it yourself, you will need a 7/8" wrench, and a new o2 sensor, or flex pipe, or manifold depending on what's broke. Do NOT touch the tip of the new or old o2 sensor to ANYTHING when you take it out or install it or it will be ruined permanently. Run the car until it's at it's normal operating temperature. Raise the vehicle, and take the o2 sensor out of the car (see below to understand which one) using the 7/8" wrench or if you got fancy and bought an 02 sensor tool... use it.

Replace whatever parts are bad (manifold or pipe) or just replace the sensor you need. Then restart the car and take it to a parts store and have them clear the code. The code (and check engine light) won't return right away, it usually takes a few days. If you did everything right you should be good. If not, it's not a terribly expensive job to have done and by now you should be able to explain to them what's wrong based on what you found when you looked at the car. Just tell them everything you checked and what you saw.

Education: I'm not sure where that half baked answer about o2 sensor 1 being near cylinder one came from but here's the real deal.

Sensor 1 is always BEFORE the catalytic converter
Sensor 2 is always AFTER the catalytic converter

Bank 1 and Bank 2 refer to which SIDE of the exhaust on 6 and 8 cylinder engines. Bank 1 is usually left side, Bank 2 is usually right side.

So... O2 sensor B1S1 refers to the O2 sensor BEFORE the converter on the LEFT side of the motor.

Torque in two to three stages.
Connecting rods are 24-26 lb.ft.
Main bearing caps are 41-44 lb.ft.

My hyundai accent giving p1801 and p1805 the car dont start what should i do.regds Maxwell,

Let's see if this helps:

Have you checked the belt for cracks? Also, you never want to use the spray on the belt. If the belt is new, then you want to check the pulleys for dirt or old rubber that melted to the pulley. A good way to clean the pulleys is to remove the belt and use soapy water and a tooth brush and clean each pulley. If you are having a hard time getting all the junk off, you could try using a pick or a screwdriver and CAREFULLY pressing it against each pulley until they are clean. If that doesn't work then you could either have a misalignment of pulleys, wrong belt, or possibly fluids leaking on belt.
