CHECK ENGINE LIGHT ON ( )

2000 Toyota Corolla

Hi

My car is 2000 corolla and It has check engine light on. I check the code and it is P1656 ( OCV circuit malfunction). Can you tell me what is that code mean? And what part should I change? Also, where is the gas fillter for this car? I see 1 filter behind the Evap cap ( green cap) on the fuel line but not sure about it. Can you help me out. Thank you.

Start with checking the coolant level of the car. I would be that they might have put in a new water pump while they were in the area. Check the coolant level, then with the engine warm, crack open a bleeder on the cooling system to allow air out of the system. See how that works for starters. Then look around and check out the vacuum lines for any leaks.
