    Default City 2007 Heat circuit damaged

    Dear friends,

    Due to an accident, my car was damaged last week as it ran over big rocks.
    Engine check light is continuously showing. Silencer pipes were damaged.
    Silencer pipes are repaired but after computerised diagnostic, it showed that heat circuit is damaged. Otherwise car is running fine except it is using too much petrol.

    I have contacted atlas honda, they are saying it will cost around 22000. Please help regarding the issue.

    your o2 sensor heat circuit has gone bad, its related to the exhaust, its the cause of poor fuel economy, have the heat circuit checked and also see the output graph of o2 sensor, if its voltage is fluctuating then its functioning correctly and you can fix the heater circuit and it wont be expensive, if o2 sensor is static or not working then honda atlas are correct as thats how much a new o2 sensor + heater circuit will cost.

    same place where you got the car OBD scanned, there will be a option in the scanner to show a output voltage graph of o2sensor,in simple words if its fluctuates then sensor is working, if its static then sensor is bad, more can be told by looking at the readings. goto any person with a decent obd scanner, even if you cant have a graph see the voltage value form the o2 sensor, any generic scanner will also show you that.

    The heater circuit is separate from the output of the o2 sensor.

    Check the internal resistance of the heater coil in the o2 sensor, it should be 13 ohms, test the wiring to it also, the positive is supplied with key and the negative leg is controlled by the ECU, it also measures the amp pull at different times to determine if the sensor is cold.

    The swing wave only shows the output of the o2 sensor "sensor" circuit.

    Xulfiqar bhai, please refer any reliable place to check it?

    If it is detected faulty, any other way to resolve the issue other than buying new circuit from atlas honda.

    thats what i mean as i wrote have the heater circuit checked and also...... functioning correctly and you can fix the heater circuit and it wont be expensive....

    reaosn i wrote about the graph was as honda atlas was billing him for 22,000 so they must think o2 sensor has also gone bad,

    to the op sorry for any miscommunication.

    We did not diagnosed from atlas honda, we only asked about the rate of new circuit from them.

    So the thing is i will go again to the diagnosis wala and ask him about the details.

    It would be heater circuit. Your primary or Secondary O2 sensor is doomed. Get new one for some 10k or get used one for 1500 and make sure it works no gurantee on used ones

    used ones are 90% of the times junk items which dont work. - In most cases a faulty o2 sensor heater is a broken wire - which is easy work to detect and repair. If the circuit is clean to the sensor connector then you need to buy the sensor itself.

    why are you guys referring to it as "heater circuit"

    the heater circuit is integrated into the o2 sensor itself, test the wiring to the sensor, 2 wires control the heater, one is 12 V +ve supply to the heater, the other is the ECU control which controls the ground leg (which in turn heats up the sensor element)

    most of the time such issue is a damaged wire in the loom, its not very hard to repair.

    Issue is resolved, I have bought kabli o2 sensor from shersha for Rs. 4500. Searched almost 30 shops for this but atlast was found on one shop. It is not commonly available. Car is running fine now. thanks for your response.
