Your gas mileage will also be terrible, so you should try and fix it as soon as you can. Unfortunately, the average replacement cost is around $2,000 and you can't do it yourself unless you're an experienced mechanic.
P0077 Possible Solution:
Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft. If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.
P0077 Code Meaning :
|OBD-II Diagnostic Powertrain (P) Trouble Code For Engine||Intake Valve Control Solenoid Circuit Low||Ambient Air Temperature Sensor Circuit Low||Cylinder 10 Contribution/balance Fault||Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical|
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate.
P0077 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0077 OBD-II Trouble Code Intake Valve Control Solenoid Circuit High Bank 1 is the generic definition for the P0077; however your vehicles manufacturer may have a different definition and information for the P0077 code. P0077 code.
Reason For P0077 CodeThe reason of P0077 OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low.
P0077 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
