P0734 Hyundai accent 2003


code p 0734 refers to gear 4--incorrect ratio===causes --wiring---TR sensor/ switch---shift solenoids---transmission mechanical fault
I would check the operation of the transmission ration sensor/switch first as that is the most likely place that the fault is
check engine lights are not solely for the engine but report on transmission problems as well
a transmission mechanical fault is the absolute last that you should consider because the transmission will revert to normal operations until it selects gear 4 which indicates sensor or solenoid problem

Hoe to fix Chrysler 300M: 99 30m Chrysler have the codes po700,po734,po733,po122,po113,po108


codes PO700, PO733, PO734 are all transmission codes all have to do with inproper outputshaft speed could be a bad outut shaft sensor but most likely the transmission is slipping, and that is not good if the transmission is shipping you will need to replace it, but try chaning the fluid and filter and and see if that does not take care of the problem.

code PO122 is the TPS sensor, code PO108 is the MAP sensor the MAP sensor can set the TPS code but the TPS can not set the MAP code so i would start with the MAP sensor ..... code PO113 is the intake air temp. sensor check the wiring on the top of the engine to make suer there is not a bad spot in the harness if all looks good then replace the sensor, but the way all 3 sensors use a commoin ground circuit so check the wiring before you replace any of the sensors......good luck

Code p1128 weak mixture lose power on inclines engine light on melts spark plugs vehicle hyundia accent 2001


Go to www.hmaservice.com and register your vehicle by VIN #..
you'll then have access to wiring diagrams, shop manuals,
service bulletins, illustrations, etc. To diagnose a 2000 or 2001 1.5L Accent Diagnostic Trouble Code (DTC) P1128 (FUEL SYSTEM LEAN -- PART LOAD), check the following:
  • Check the intake system for air leaks.
  • Check that the Mass Air Flow (MAF) Sensor (P/N 28164-22610) operation meets the specifications listed below. If the MAF sensor output is significantly lower than the reference value (10% or more), then replace the MAF sensor.

The check engine light came on, the code reader indicates PO122. What is the issue and what can I do. I am on a road trip.


A GM PO122 code means that the the car's computer has detected that the TPS ( throttle position sensor) is reporting too low a voltage.

2001 hyundai accent 1.5l codes 300 301 303 have ck tim belt,comp at 200 psi .replace spark plugs,crank sensor ,fuel pump&filter .will start then die


Replace the throttle position sensor (TPS) (since you've checked/replaced anything else which could be causing this problem - except WIRING). Reinspect all wiring & connectors/connections before replacing the TPS. Also, I've seen (on occasion, a faulty "Main Relay" create the condition you describe). Suppose you have a faulty ignition switch (ignition key). When placed in the 'START' position, the engine starts normally, BUT, when you release IT to the 'RUN' position, the engine dies - CLUE?

I have a 98 Hyundai accent. Won't accelerate over 50mph


the o2 sensor will cause overfuelling and an improper throttle position.
the heater circuit has 12v,and the other 2 wires are a reference voltage.
you need to use a scanner and look at the live data to see what the 02 sensor is doing.
after battery disconnect,the monitors have to set using a drive cycle of which you can get from hyundai.Typically to set the 02 heater circuit,the car has to idle for 2 minutes when cold,and then drive at 55mph for 3 minutes with the a/c on.
