Engine light on and codes P0018 and P0050

Hello,

These codes are for the crankshaft sensor and the O2 sensor, I would replace both and clear the codes to see what happens. Here are guides and instructions to help you fix the problem:

P0050 HO2S Heater Control Circuit (Bank 2 Sensor 1) - OBD-Codes

P0018 Crankshaft Position - Camshaft Position Correlation (Bank 2)

This guide will walk you through the oxygen sensor replacement:
