P0874 Engine Trouble Code

Meaning of P0874 engine trouble code is a kind of powertrain trouble code and P0874 if your catalytic convertor fails completely, you eventually won't be able to keep the car running. 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.

P0874 Possible Solution:

P0874 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.

P0874 Code Meaning :

P 0 8 7 4
OBD-II Diagnostic Powertrain (P) Trouble Code For Engine Intake Valve Control Solenoid Circuit Low Engine Oil Temperature Sensor Malfunction Cylinder 10 Contribution/balance Fault Timing Reference High Resolution Signal A Too Many Pulses

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.

P0874 OBD-II Diagnostic Powertrain (P) Trouble Code Description

P0874 engine trouble code is about Timing Reference High Resolution Signal A Too Many Pulses.

Main reason For P0874 Code

The reason of P0874 OBD-II Engine Trouble Code is Engine Oil Temperature Sensor Malfunction.

P0874 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.
