Can P0134 cause misfire?
Honda recommends replacing the A/F sensor and installing a sub-harness kit as a solution. In some Hyundai V6 engines, a faulty oxygen sensor could cause the code P0134 along with misfiring codes (P030x) and rich condition; replacing the oxygen sensor should solve the problem.
What causes O2 sensor to have no activity?
If the O2 sensor isn’t reacting at all, it can be due to a dead sensor, a shorted or severed O2 signal wire, or, in some cases, it can be due to a bad O2 reference ground. Conventional O2 sensors have four wires: the two heater wires (one of which is grounded by the ECM/PCM to control the heater).
What causes P0134 code?
Code P0134 is triggered when your vehicle’s O2 sensor (bank 1, sensor 1) is malfunctioning. The Engine Control Module (ECM) detects that the Oxygen (O2) sensor is at a standstill and is not accurately reading the amount of oxygen in the exhaust.
