2004 Lexus ES330 ProblemsCheck Engine Light With Code P0171 and/or P0174
The Check Engine Light may illuminate with codes P0171 and/or P0174 due to a lean running engine. Symptoms may include: Hesitation on acceleration, lack of power, and poor fuel mileage. This is commonly caused by a dirty mass airflow sensor. Our technicians tell us the sensor may be cleaned using an approved cleaner but replacement is often required to correct this issue.
A vibration may be noted in the brake pedal or steering wheel when the brakes are applied. This is commonly caused by warped front brake rotors. The affected rotors must be re-machined or replaced to correct this concern.
The Check Engine Light may illuminate due to an O2 sensor heater fault. Most commonly the affected O2 sensor will need to be replaced to correct this concern.

2004 Lexus ES330 RecallsVarious Issues Due to Failed Crankshaft Pulley
The amount of adhesive applied between the inner and outer parts of the crankshaft pulley may be inadequate. If this is the case, the outer ring may become misaligned and/or not properly rotate with the inner ring, causing an abnormal noise and/or illumination of the Check Engine Light. In some cases, the power steering belt could come off resulting in a loss of power steering assist, increasing the risk of a crash. Dealers will inspect the crankshaft pulley and replace it if necessary.
