Loaction 2004 Dodge Durango code P0058


following answer courtesy of OBD-CODES,com P0058 HO2S Heater Control Circuit High (Bank 2 Sensor 2) OBD-II Trouble Code Technical Description Article by Dale Dale Toalston ASE Certified Technician Generic: HO2S Heater Control Circuit High (Bank 2 Sensor 2) Nissan: Heated oxygen sensor (HO2S) 2 Bank 2 - heater voltage high What does that mean? This code is a generic powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may be slightly different depending on the model. Oxygen sensors with a heating element are common on today's engines. Heated Oxygen sensors (HO2S) are inputs used by the PCM (Powertrain Control Module) to determine oxygen content in the exhaust system. The PCM uses the information gained from the Bank 2,2 HO2S mainly to monitor the efficiency of the catalytic converter. Integral to this sensor is a heater element. While in pre-OBD II vehicles an Oxygen sensor was a one wire sensor, now they are more commonly 4 wire sensors: Two dedicated to the oxygen sensor and two dedicated to the heater element. The oxygen sensor heater basically decreases the time needed to achieve closed loop. The PCM controls the heater on-time. The PCM also continuously monitors the heater circuits for abnormal voltages or in some cases, even abnormal amperages. Depending on the make of vehicle, the Oxygen sensor heater is controlled one of two ways. (1) The PCM directly controls the voltage feed to the heater either directly or via a HO2S relay and a ground is supplied from the vehicle's common ground. (2) There is a fused 12 volt Battery feed (B+) that feeds 12 volts to the heater element anytime the ignition is on and the control of the heater is done by a driver in the PCM which controls the ground side of the heater circuit. Finding out which one you have is important because the PCM activates the heater under various circumstances. If the PCM detects an abnormally high voltage condition on the heater circuit, P0058 may set. This code is only referring to the heating circuitry half of the Oxygen sensor. Bank 2 is the side of the engine that does not contain cylinder #1. Symptoms Symptoms of a P0058 DTC may include: MIL (Malfunction indicator lamp) illumination There would likely be no other symptoms. Causes Potential causes of a P0058 code include: Faulty Bank 2,2 HO2S (Heated Oxygen sensor) Open in the heater control circuit (12 volt PCM controlled systems) Short to B+ (battery voltage) in the heater control circuit (12 volt PCM controlled systems) Open ground circuit (12 volt PCM controlled systems) Short to ground on heater control circuit (On PCM ground controlled systems) Possible Solutions First, do a visual inspection of the Bank 2, 2 HO2S (heated oxygen sensor) and it's wiring harness. If there is any damage to the sensor or any damage to the wiring, fix it as needed. Check for bare wires where wiring enters sensor. This often can fatigue and cause shorts. Make sure wiring is routed away from exhaust. Repair wiring or replace sensor as necessary If all appears okay, unplug the Bank 2,2 HO2S and verify that there is 12 volts B+ present with the key on engine off, (or ground is present, depending on the system). Verify the heater control (ground) circuit is intact. If so, remove the o2 sensor and inspect for damage. If you have access to resistance specifications you can use a Ohmmeter to perform a resistance test of the heater element. In

Is p0052 a fuse problem or a o 2 sensor


P0052 DTC trouble code may be caused by one or more of the following:
A short in the heater circuit in the sensor.
A failed O2 sensor heater.
Wiring/connectors broken/frayed leading to sensor and/or relay.
Failed PCM/ECM.

Oxygen sensor, the powertrain control module controls the electrical circuit for the oxygen sensor heater. where do you find this and the relay


the heated oxygen sensor(HO2S) is located in the exhaust manifold/s before the cat converter/s
O2 sensors are located after the cat converters
the power train is the engine and transmission unit and the control for the sensors is the ECM
the major problem is the wires in the HO2S as they are fragile and break close to the sensor very easily

01 vw Jetta trubo 2.0 code p1113



Trouble Code: P1113

O2 Control (Bank 1 Sensor 1) Internal Resistance Too High
Possible Causes:


Oxygen sensor (before catalytic converter) is faulty. Oxygen sensor (behind catalytic converter) is faulty. Oxygen sensor heater (before catalytic converter) is faulty. Oxygen sensor heater (behind catalytic converter) is faulty. Circuit wiring has a short to power or ground. Engine Component Power Supply Relay is faulty . E-box fuses for oxygen sensor are faulty . Leaks present in the exhaust manifold or exhaust pipes. HO2S signal wire and ground wire crossed in connector . HO2S element is fuel contaminated or has failed. ECM has failed .Here is what is listed.

1995 Cadi SLS Codes, P0030 & P0036, Ckt Fuse or Relay Defective, checked fuse ok, where is relay located?


Hi there,

P0030 = HO2S Heater Control Circuit (Bank 1 Sensor 1) - No.1 Heated Oxygen sensor on bank 1.
P0036 = HO2S Heater Control Circuit (Bank 1 Sensor 2) - No. 2 Heated Oxygen sensor on bank 1

For both of these to trigger on the same bank, means most likely an Open or Short to Ground condition (somewhere on the Bank 1 circuit) stopping the HO2 sensors from reaching their working temperature.

Check the following in this order:

1) Using a multimeter, check 'continuity' of the Oxygen circuit FUSE terminals (don't rely on visual inspection alone) or replace fuse with a known good one.
2) Check for moisture getting into both oxygen sensor connector terminals (bank 1).
3) Check for good connection at Oxygen sensors (bank 1).
3) Have both heated oxygen sensors on Bank 1 tested (ensure their values are to specification).
4) Check HO2 pin-outs of the PCM for correct voltage.

Only replace the HO2 sensors as a last resort (if out of spec).

Then engine department relay centre & fusebox location is behind the washer bottle, but I believe the HO2 sensors are connected direct to the PCM, not a relay.

Cheers,

There is a fault with the inbuilt heater in the oxygen sensor, before the catalytic converter, on the exhaust pipe the same side of the engine as cylinder 1. The oxygen sensor has four wires within the cable sheath to the top of it. Two of the wires will share the same color. These wires supply power to an internal heating element wire within the sensor. Follow the cable from the oxygen sensor to the connector, you can do a lot testing here. Check the resistance between the two 'same coloured ' wires. The resistance is low, somewhere between 1 and 10 ohms. If there is no continuity (infinite resistance) then this is the fault and the sensor needs to be replaced. The codes: P0030 the oxygen sensor heater relay is at fault P0053 Oxygen heater resistance error P0135 Sensor 1 bank 1 error You are looking at replacement. A further confirmation take the connection from sensor 1 bank 1 and swap it with the sensor 1 bank 2 on the other side of the engine. The codes should 'transfer' and show P0036; P0059 and P0141.

Where is the oxygen sensor heater circuit 1 Bank 1 for a 03 Toyota Avalon XLS?


2695479270043892667s600x600q85.jpg
Above is the sensor itself on an 03 Avalon.

If the heater circuit has no activity check the relay located inside the engine room junction box JB shown below.
