Question about 2000 Hyundai Accent

1 Answer

Please, i need help. Mi car mark 11 codes in electronic checking

My car sends more than 11 codes of sensors damaged. Now you change the card and take you to two more workshops to review the rulings that gave me the car. The Electromechanical say they do not know me because sends so many mistakes and that even so the car turn.

Not if you can help me or send codes on the card to confirm the damage, as the mechanic has a list of codes but these codes to mark my car are not registered.

Please, you do not know what to do or who to go to. I like to see if I can give advice or help.

thank you very much

Sounds like you have a europeon model ,built for the europeon market where its permitted to encrypt the software to stop general garages from being able to diagnose and repair the car.only answer ??become a golden egg layer for main dealer sorry about this ,but the problem of encrypted software is becoming a big thing here causing the demise of the small general garage.

Do I need a new PCM or just change the gov.pressure sensor.

Arcing is usually a bad sign. Was the wire connected to the sensor input of the PCM or to the sensor? If connected to the sensor you probably need a new sensor. But I'm guessing it was the one going to the PCM. Sounds like more than just a temp sens fault.

What make / model is your truck? Fault codes starting with 1 are manufacturer specific codes. Read more at: Copyright
How did it behave before this? Why did you change the sensor? What fault code? If it was already like this then it could be another sensor.
Is it now much worse? If so it could be damage to the PCM, sorry to say.
Some PCMs are better protected than others but most don't like 12v on a sensor input and some damage can be done. Some designs let the 12v get through to the processor, which usually runs at 5v or even 3.3v, and burns out in milliseconds at 12v, but I think most limit any damage to the input circuitry. If you're still getting fault codes it's a sign the processor is still working.
So it may be possible to repair the PCM if it's damaged, it's possible that the damage is obvious to a good electronics tech if the input is protected. (protected can mean only a small relatively easily replaced part of the circuit around the input burns out, not the whole microprocessor). Identify the temp sense input pin and trace where it goes, look for burnt tracks, resistors, etc... Don't try to fix it yourself if you are not familiar with electronics repairs, it's easy to damage a PCB and you might need to exchange it in good condition if you are going to get another one.
Good luck.

2003 ford taurus idle problems had trouble codes

A code P0174 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor. and your solutions are.
    • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner . Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
    • Inspect all vacuum and PCV hoses, replace if necessary
    • Check for a dirty fuel filter and proper fuel pressure

97 F150 4.6 4X4 supercab , code 0153 O2 sensor slow response,Bank 2 sensor 1. Is this the passenger side and sensor before the cat? Also code 1151 I have no reference for this code,not sure what it is....

SECTION 303-14: Electronic Engine Controls 2000 Expedition/Navigator Workshop Manual DESCRIPTION AND OPERATION Electronic Engine Controls The electronic engine controls consist of the:
  • powertrain control module (PCM)
  • throttle position (TP) sensor
  • idle air control (IAC) valve
  • engine coolant temperature (ECT) sensor
  • camshaft position (CMP) sensor
  • crankshaft position (CKP) sensor
  • mass air flow (MAF) sensor
  • intake air temperature (IAT) sensor
  • heated oxygen sensor (HO2S)
  • knock sensor (KS)
  • vehicle speed sensor (VSS)
  • cylinder head temperature (CHT) sensor
The PCM needs the following inputs to calibrate the engine correctly:
  • engine rpm
  • engine coolant temperature
  • amount of engine detonation
  • crankshaft position
  • air temperature
  • throttle position
  • cylinder head temperature
  • mass air flow
The TP sensor:
  • sends the PCM a signal indicating the throttle plate angle.
  • is the main input to the PCM from the driver.
The IAC valve:
  • controls bypass air around the throttle plate at low speeds.
  • is controlled by the PCM.
The ECT sensor:
  • sends the PCM a signal indicating engine temperature.
  • resistance decreases as coolant temperature increases.
The CMP sensor:
  • sends the PCM a signal indicating camshaft position used for fuel synchronization.
The CKP sensor:
  • sends the PCM a signal indicating crankshaft position.
  • is essential for calculating spark timing
The MAF sensor:
  • sends the PCM a signal indicating mass airflow rate of air entering the engine.
The IAT sensor:
  • sends the PCM a signal indicating the temperature of the air entering the engine.
  • resistance decreases as temperature increases.
The HO2S:
  • has the ability to create a voltage signal dependent on exhaust oxygen content.
  • provides feedback information to the PCM used to calculate fuel delivery.
The 4.6L KS is located in the lifter valley. The 5.4L has a unique linear KS located in the lifter valley.
  • The KS sends a signal to the PCM indicating engine detonation.
The CHT sensor:
  • is mounted into the wall of the cylinder head and is not connected to any coolant passages.
  • sends a signal to the PCM indicating cylinder head temperature.
    • If the temperature exceeds 126°C (258°F) 5.4L, 130°C (265°F) 4.6L, the PCM disables four fuel injectors at a time. The PCM will alternate which four fuel injectors are disabled every 32 engine cycles. The four cylinders the are not being fuel injected act as air pumps to aid in cooling the engine.
    • If the temperature exceeds 154°C (310°F) 5.4L, 166°C (330°F) 4.6L, the PCM disables all of the fuel injectors until the engine temperature drops below , 154°C (310°F) 5.4L, 153°C (308°F) 4.6L.
The VSS:
  • is gear driven by the transmission.
  • sends a signal to the PCM indicating vehicle speed. For additional information, refer to Section 307-01A R4100 and/or Section 307-01B 4R70W
P1151 - Lack of HO2S-21 Switch, Sensor Indicates Lean A HEGO sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC P1130

P1130 - Lack of HO2S-11 Switch, Fuel Trim at Limit The HEGO Sensor is monitored for switching. The test fails when the HO2S fails to switch due to circuit or fuel at or exceeding a calibrated limit.
  • Electrical:
    • Short to VPWR in harness or HO2S
    • Water in harness connector
    • Open/Shorted HO2S circuit
    • Corrosion or poor mating terminals and wiring
    • Damaged HO2S
    • Damaged PCM
  • Fuel System:
    • Excessive fuel pressure
    • Leaking/contaminated fuel injectors
    • Leaking fuel pressure regulator
    • Low fuel pressure or running out of fuel
    • Vapor recovery system
  • Induction System:
    • Air leaks after the MAF
    • Vacuum Leaks
    • PCV system
    • Improperly seated engine oil dipstick
  • EGR System:
    • Leaking gasket
    • Stuck EGR valve
    • Leaking diaphragm or EVR
  • Base Engine:
    • Oil overfill
    • Cam timing
    • Cylinder compression
    • Exhaust leaks before or near the HO2S(s)
A fuel control HO2S PID switching across 0.45 volt from 0.2 to 0.9 volt indicates a normal switching HO2S.

P0153 - HO2S Sensor Circuit Slow Response (HO2S-21) See DTC P0133

P0133 - HO2S Sensor Circuit Slow Response (HO2S-11) The HEGO Monitor checks the HO2S Sensor frequency and amplitude. If during testing the frequency and amplitude were to fall below a calibrated limit, the test will fail.
  • Contaminated HO2S sensor.
  • Exhaust leaks.
  • Shorted /open wiring.
  • Improper fueling.
  • MAF sensor.
  • Deteriorating HO2S sensor.
  • Inlet air leaks.
Access HO2S test results from the Generic OBD-II menu to verify DTC.

1995 Jeep C. 4.0l 6cyl stalling & dies. Random. Getting worse.

Before you encounter this problem do you have problem starting the Jeep?

Crank angle sensor and Idle air control valve are the most common parts failure for 150,000+ miles vehicle.

I would clean the spring,plunger and the interior pathway of the IAC. The IAC is the 4 wire electronic motor that adjust the idle.

Since you has 180K miles,the CAS should be replace.

The .Automatic Shutdown relay (ASD) (Relay #4/inside the fuse box) can be damage also.

Check out these three trouble spots and post a comment.

I will follow up on it later.

Fluctuation on the oil pressure gauge reading

The oil pressure sending unit is a sensor with an internal diaphragm, if the internal diaphragm is damaged , or the line to the diaphragm is blocked you can get this kind of fluctuation on the oil pressure gauge.

The oil pressure value must be read by installing a mechanical gauge near to the oil pressure switch and checking the pressure.

If pressure is ok, replace the sending unit. If there is a real pressure drop, check the oil pump.

If you still get fluctualtion after replacing the oil pressure sending unit, replace the oil pressure gauge.
