Car sometimes wont start unless you spray starter fluid, just replaced filter. oem codes are p0734 and p1401


P0734 = 4th gear incorrect ratio (that's the torque converter 'lock-up' clutch - inside the converter).
P1401 = doesn't exist for 2002 Hyundai Accent's
P1401 exists for 2000 Accent = DM-TL Air Pump Motor Curent Draw is higher or lower than expected (normal is 17-36 mA). DM-TL = Diagnostic Module for Tank Leakage & is part of the Evaporative Emissions Control System.

These two DTC's are not associated/part of the Accent's Engine Managemenet System (EMS).
Best to have a qualified/certified Hyundai Service Technician properly diagnose this starting problem with your vehicle.

Mi hyundai accent GLS 2002 tiene el check encendido y tiene los errores p1401 y el p0442, que puede ser y como puedo solucionarlo, ademas la luz del dasch se apaga y se enciende constantemente que puede...


The 2000 model year Accent adopts a different "pressurized" leak check system capable of detecting a 0.020" (0.5 mm) diameter leak (previous Hyundai systems detect a 0.040" [1mm] diameter leak using engine vacuum). The new system uses a Diagnostic Module for Tank Leakage (DM-TL) to close and pressurize the fuel evaporative emissions system. The DM-TL replaces the fuel tank pressure sensor and the canister close valve from previous systems. Other significant changes were made to the system logic, including several new diagnostic trouble codes. It compares the differences between the 2000 model year Accent and previous evaporative emission systems... Que puede ser? Tiene dos opciones. Primero, puede pagar que un tecnico diaga el problema (exactamente) o sigue, secudariamente, su adivnaza.

Check engine light says on . code 1401,what does it mean?


P1401 - DM-TL air pump motor current draw is higher or lower than expected (normal = 17-36 mA).

This is an electrical issue with the pump, it's not related to a leak in the evaporative emission control system.

2000 Hyundai Accent


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
