2001 hyundai accent obd 11 code p1402 - 2001 Hyundai Accent

code p 1402 refers to fuel tank leakage diagnostic module--motor malfunction===causes --fuel tank leakage motor diagnostic module motor
code p 1403 refers to the fuel tank diagnostic module ---valve malfunction
go to a service dealer and have the unit tested
it is possible that by replacing or cleaning the valve section , the problem will be fixed

Type: OBD & your codes

OBD PO 733

It's all on the internet on hundreds of sites

OBD II codes are specific to manufacturers and often specific vehicles. A Hyundai Accent P0650 may not be the same as a Hyundai Sonata P0650 because Hyundai loaded more diagnostic codes into the upscale Sonata.

Check with AZone or similar, they'll tell you the code description, and give you possible suspect causes to check.

you wont know until you have it scanned with OBD II scanner...run codes

i think you need to go back to basics.if here is no obd fault codes in the system to give you a clue. then use a multimeter and have a good look at the wiring for corroded connectors etc. including the fuel pump?

Most of the time they mean:
p0441 = Evaporative Emission System Incorrect Purge Flow
p0422 = Evaporative Emission Control System Leak Detected (small leak)

MOre info at http://www.obd-codes.com/p0442

The primary causes of inability to attain high rpm are clogged exhaust (usually a catalytic converter) and low fuel pressure. This can also be caused by a malfunctioning air flow sensor or a mistimed camshaft

Hello there! Here is a break down of the majority of the codes you posted and an explanation.
First of al the P1402 + P1403+ P0441 are all connected.
P1402- DMTL Motor Circuit
P1403- DMTL Valve
P0441- Gross evaportive emissons leak (of the least concern of all codes)
P1402 +P1403 are both in connection with the Charcoal canister. Generally over fueling a vehicle cause these codes. Hyundai's are particular prone to this issue due to emissons control locations. Simply put a DTML is a sensor. There is 2 of these particular ones on your car. One mounted at the engine and one connected to the throttle body. Fuel more than likely has contaminated the charcoal canister. If only one of the codes were set i'd assume it was just a wiring issue. More than likely the canister and solonoid need to be replaced. Obviously checking the wiring should be done first. Corrison or a broken wire also could cause these codes to trip.
P1632- Transmission Temp Pull-Up Resistor issue. I am not a Hyundai Tech so I don't have allot of experiance with there transmisson codes. However the same code with same function is listed on the F-body site(GM). I would correct the other 3 and go from there. I assure you that poor engine performance would definately cause transmisson issues, especially with the shift points. Especially with a transmisson like yours that is totally electrically controlled. Please let me know if any of this makes more sense. If need be I can elborate more.

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

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

perform the suggested repair
1. inspect for water in the dmtl by removing the 90° air inlet elbow and looking into the air chamber. if water or corrosion is present, replace the dm-tl p/n 31440-25500; air filterp/n 31453-25500; and pipe assembly p/n 31454-25500if corrosion is in the pipe. see detailed instructions on page3 for air filter replacement.
2. inspect for underbody coating sprayed into connector m52 at dm-tl. if underbody coating is present on the male or female connector, spray with electrical contact cleaner to remove the undercoating.

air filter (dm-tl) replacement instructions

1. disconnect the 90° elbow from the top of the dmtl and insert a clean rag into either the elbow or thedmtl inlet connector.
2. disconnect the dmtl electrical connector.
   
1. disconnect the 2 hoses at the front of the canister (caution: silicone hoses tear/puncture easily).
   
2. remove canister assembly and dm-tl as a unit (3 mounting nuts).
   
3. disconnect the 2 hoses from the metal transfer pipes.
   
4. remove the canister, air filter, and metal tube assembly from the canister protector by removing the 3 mounting nuts.
   
5. disconnect the hose at the air filter.
   
6. remove the air filter mounting nut and remove the air filter.
   
7. install a new air filter.
   
8. reassemble in reverse order.
