2012 Hyundai Sonata Hybrid

I have code p1777, PCM out put malfunction.
Where I can start to check? What that code means?
thank you


Code P1777 – OPU Power Control Circuit Failure

Code P1777 is set and sent to the PCM/TCM when OPU detect error into OPU internal power control circuit.

Possible Causes:

  1. OPU Power stack error
  2. EOP stuck error
  3. 3-phase wiring short to VB,GND

OPU Power Control Unit Location

OPU Power Control Unit Location

Code P1777 General Description

The HEV uses the hydraulic pressure that in addition to mechanical main hydraulic pump EOP (Electric oil pump) controlled by OPU (oil pump unit) to take command by PCM/TCM generates oil pressure to operate clutch and U/D brake.

When low speed driving or engine auto stop regardless of driving mode (EV mode or HEV), when hydraulic pressure becomes low because of mechanical main hydraulic pump rotation in low speed or stop, OPU supplies hydraulic pressure on U?D brake by operating EOP in order to protect Friction Element.

When shifting the driving mode from EV mode to HIV mode, EOP supplies hydraulic pressure to the engine clutch in order to use engine power when the driving mode shift is completed (Engine clutch: wet type multiple disk clutch that connect or disconnect the engine power between engine input shaft and transaxle input shaft)

What to check

According to the Manual you are to inspect the terminal and connectors first. Then check the component itself.

  • Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage.
  • In order to check the component, the manual advises to clear the code(with a scantool) after cycling the IG on and off two or three times. If the same code returns, substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM.

Code P0340. Looking for diagram for plug. Last mechanic broke connector and spliced wrong connector on and crossed wires. Need to know what wires go where on sensor. Don’t want to short out new sensor. Car starts then dies in 3 seconds. Get 2 diagnostic trouble codes both P0340


Code P0340 Hyundai

Description: Camshaft Position Sensor A Circuit (Bank 1 Or Single Sensor)

Probable Causes:

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty

I have two codes, one for fuel tank pressure sensor and for oxygen sensor bank one. Ive replaced ftps and both oxygen sensors twice and still get the codes. could there be something else wrong that wont kick these codes out?


First I will need the two codes… post in the comments below.

2009 Hyundai i20

Hi – I am desperately searching for the Wiring diagram for a 2009 Hyundai i20 1.2 Classic vehicle. I need the diagrams for the Engine Bay as I had a loom fire and need to replace the cables that have been burnt.


Hyundai i20 wiring diagram

At this time we only have access to US Domestic and import model diagrams. I see you have requested this information from several places over the internet. Unfortunately no one seems to have this diagram available in free form.

This may be an instance where you will need to contact the service manager at your local dealership and request the information from them. Some may even be able to present you with the wiring diagrams for free. You never know unless you ask.

2011 Hyundai Active

Put the key in the ignition nothing happens

I have a 2011 Hyundai i20 active 2dr 1.4 manual shift. Just wondering if anyone has encountered something similar with any of their cars. When I put the key in the ignition nothing happens. The gauge cluster doesn’t turn on. Nor does the radio, ac controls or power through the USB port or 12v port. However the door open light comes up on the dash. And the park lights come on when you turn the lights on.

The central locking still works as does the alarm (horn beeps) however using the horn wont make it beep. I’ve checked the fuses and they are fine. I initially thought it was a blown relay as my dad pulled the ecu relay and flicked it, plugged it back in and off I went. Then this morning when I put the key in after dropping my daughter off at daycare it did the same thing again. Also does anyone know where to find a wiring diagram for the relays so I can try finding an aftermarket part.


My guess would be a faulty ignition switch since nothing turns on except the stuff that would come on with out the key present such as the headlights.

Hyundai Accent

My car stopped starting last week. The battery is less than 4 months old. I can jump the car and it will run indefinitely with no power problems. Whenever I turn off the engine it will not start back up. It makes a clicking noise as long as I keep the key turned. I took the car to Autozone and they checked the battery, starter and alternator. They said the alternator was bad. I replaced the alternator, but the car still will not start without a jump. Took the car back to Autozone and they again said it was the alternator. I checked the wiring(except at the starter because it is hard to get to), replaced the terminals on the wiring to the battery. Checked the ground wire. Nothing I have done seems to solve the problem. It just clicks when I try and start it.


Replace the BATTERY!  It doesn’t matter how old it is, if its bad, its bad. The clicking noise is the tip off.

I am trying to reconnect the camshaft position sensor connector back up after breaking it, and I didn’t get a chance to see what positions the wires were in on the connector Harness. I have three wires. One is Brown, and two are black. Of the two black ones, one has 5 on it and the other has .5 on it. Can you help provide me with a diagram of who the wires are positioned.


On the sensor pins 1 is Black, 2 is Black and 3 is Pink. Number 2 pin Black wire connects to the PCM on pin #16. A continuity tester can be used to confirm.

CBD II codes: P0302, P0170, and P2006 Can the engine problems be resolved by using a fuel additive/cleaner and replacing the fuel filter?


I would have to say NO. You may review the code information and see it is going to take a bit more than a filter and fuel change.

  5. Powertrain or Engine Control Module faulty

Hyundai Code P0170

Fuel Trim (Bank 1)

Code P0170 Probable Causes
