P1155 Toyota -will this harm the engine if i ignore the light

Question

2001 toyota avalon will it hurt the engine if the check engine light and VSC light on

Answer 1

P1155 A/F (airflow) sensor heater circuit malfunction Bank 2 Sensor 1

Whenever the CK ENG LT is on for safety reason the ABS TRA and VSC are disabled, the reason is the vehicle is not at manufactuer specification. Anytime the CK ENG LT comes on you are out of fuel control and you will use more fuel than required.  The code you have is the heater circuit of the A / F . being sensor 1 this is for the engine mangement to help maintain fuel control. The fix is to replace the A/F sensor. in doing you will have the ABS and VSC option that are available.
