PLEASE CAN YOU TELL ME WHERE IS THE LOCATION OF THE #1 OXIGEN SENSOR OF MY DODGE CARAVAN 2002 .THANK YOU

• O2 Sensor Heater Circuit Malfunction - Bank 1 - Sensor 1
• Basically the ECM Electronic Control Unit has determined your O2 sensor is taking to long to begin reacting properly.

• The causes could be

1. O2 heater element resistance could be to high.
2. An internal short or opening in the heater element.
3. O2 heater circuit wiring with high resistance.
4. Open or short to ground in the wiring harness.

• The fixes are

1. Check the harness and connector to the O2 sensor for shorts or ground.
2. Replace that O2 sensor.

• Bank 1 sensor 1 location for this vehicle is located on the exhaust manifold back by the firewall on top of the manifold..
• Thank you for using FixYa

Regards, Tony

Dear Madam or Sir,

the code stands for:

Heated Oxigen Sensor1, Bank 1, Heater Control - circuit low.

So the heating of the O2 Sensor is faulty, you should see a mechanic to fix it.

new spark plugs basic tune up this will fix it ,then fine the small vacuum leak fix it this should take care of it.

The fuse box is located under the hood. There is component map printed on the inside of the cover. This tells you on your model where the fuse or relay is located

Both front wheel hub assembly would have those sensor they are also used for the abs. I am not sure on that year of caravans would have some on the rear wheel hub assembly also.

Thank You And Happy Motoring!!

P0152 is o2 sensor 2/1 voltage high. Sensor 2/1 is your right bank upstream o2 sensor located in the manifold. Make sure it is pluged in.

It is in side the trans on top of the valve body. Why do you think you need to replace it?

it is located on the bellhousing of the transmission it gets its signal from the flywheel.look where the transmission bolts to the engine.
