My 2012 Hyundai Electra check engine showed up. Scanned the car and got two codes: b2aaa and po711. Any ideas? My car does feel rough switching gears- it's an automatic. Mainly 1st and 2nd gears.

can be a number of problems -have the check engine light scanned most auto stores offer this service for free the code will assist in solving your problem

If the engine light is blinking you have major issues with the vehicle. Have scanned at autozone or similar for codes this will give you a idea what is wrong. Then get back to me when you have codes

Code 37 is torque converter clutch solenoid failure. Transmission wont shift in and out of overdrive.

Hi Danial, Overheating is usually something to do with the cooling system, but can be caused by a few other problems. I would check the usual problems first, such as the thermostat the radiator pressure cap, water pump and the cooling fan operation. Also check for any sins of leakage. It is a good idea to have the cooling system pressure tested at a workshop, just in case the leakage is only evident when the system has reached operating temperature. Unless the engine has been seized it would be very doubtful that a con rod has been bent, which is the rod I believe you're referring to? Regards John

You got ripped off by the mechanic. A good mechanic can pinpoint the problem by using a scan tool. Take vehicle to autozone or similar and have it scanned for codes this will give you a idea what is wrong. I believe the problem is exhaust related because of the blinking light.

time to get the engine properly scanned, real time not code scanner, then you will have the readings from sensore and actuators, diagnose from there

PO456 IS A SMALL LEAK DECTECTED IN WHATS CALLED YOUR EVAP SYSTEM PO711 IS A HEATED OXYGEN SENSOR IS RUNING TO LEAN THE EVAP SYSTEM BASICLY SUCKS GAS FUEMS OUT OF THE GAS TANK AND SENDS THEM TO BE BURNED IN AIR-FUEL INTAKE SYSTEM THEOXYGEN SENSOR CODE IS PO711 IS SHOEING UP BECAUSE INSTEAT OF SUCKING GAS VAPOR ITS SUCKING AIR MAKEING IT READ TO LEAN THE PROBLEM IS WITH A PART CALLED THE EVAP VENT SOLENOID ITS STUCK OPEN SO IT CAN;T DRAW FUEL VAPOR FROM GAS TANK SEND TO ENGINE JUST AIR AND THATS WHY YOUR 02 SENSOR IS READING LEAN CONDITITOIN HOPE THIS HELPS

PO711 means transmission fluid temperature sensor circuit range / performance

problem with the transmission

Have the transmission fluid temperature sensor checked. Might be bad.
