P046A Engine Trouble Code

Meaning of P046A engine trouble code is a kind of powertrain trouble code and P046A code can be about replacing a broken oxygen sensor can eventually lead to a busted catalytic convertor which can cost upwards of $2,000. Taking your car into a shop will cost you around $200 depending on the car. However, an oxygen sensor is easy to replace on many cars and is usually detailed in the owner's manual. If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one. Regardless of how you approach it, you should get this fixed right away.

P046A Possible Solution:

P046A Engine

The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.

Regarding the P046A code, it would probably be worthwhile to carefully inspect the wire harness near the intake manifold bracket. This is done most easily from below the car in the area near the oil filter.

P046A OBD-II Diagnostic Powertrain (P) Trouble Code Description

P046A engine trouble code is about .

Main reason For P046A Code

The reason of P046A OBD-II Engine Trouble Code is O2 Sensor Heater Circuit Malfunction.

P046A DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
