Hello,

I bought the car listed above before two weeks and now the engine light turns on so I went to AutoZone and the they scan by them scanner and the problem is:

P0443: Evap Purge solenoid control circuit malfunction.
P0135: Ho2s-11 Bank 1 Sensor 1 Heater circuit malfunction.
P0449: Evap vent solenoid control circuit malfunction.

But my car still run smooth then also Last week I went some mechanic and they said that it cost around $500.00 to $800.00. So I am student and do not have that much money, but still I am confuse. Do I really need to change this all parts or not? Please help me.

Oh we can fix it for way less, lets get started. For the P0135 heater circuit here is a guide to show you how to fix that you can get the sensor from Amazon. It is number five in the diagram below.

Here is the sensor for $27.00:

You may need to jack you car up.

You will need to clear the codes.

The auto parts can do it for you as well. By the way neither of these problems will effect the way the engine runs except for the o2 sensor heater but not much.

The other two are EVAP codes here are the locations of the solenoids inspect the wiring and then replace the units number thirteen on the diagram. Check on Amazon as well or the parts store will have them.

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
