hey if you truely think it is your egr valve unhook it and if that is the problem then when it is unhooked it should run better and the codes should not come up. hey if you cahnged the 1 o2 sensor and not the other you probably made the code for the one u repalced come up again. i would recommened that you change both of the o2 sensors at the same time. try checking if your catalatic convert is plugged. how you do this is take a dollar bill and hold it at the end of your tail pipe while it is idleing and if the dollar bill stays still you have a plugged catalatic converter.

Bank 1 is the frt side exhaust manifold (did they say bank 1 sensor 1?),you can start by replacing that sensor,i would check the intake for leaks ,the gm 6cly. are known for bad intake gaskets,you will see oil coming out form the frt or rear of the intake,also check your atifreeze overflow bottle for bronwish sludge,which means that the oil is mixing with the antifreeze.A leaking intake could cause that lean condition.

SOURCE: Code: P0133 - O2 Sensor Circuit Slow Response Bank 1 Sensor 1

is this a 4 or 6 cylinder?
if a 4 cylinder it will only have 2 o2 sensors
V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor.
1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.

if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.

I have a 06 Corolla that is giving a P0037 code I have replaced the Oxygen sensor closest to the Catalytic converter Twice


it should be the o2 after cat converter ----and the following information courtesy of OBDP0037 HO2S Heater Control Circuit Low B1S2 OBD-II Trouble Code Technical Description Article by Dale Dale Toalston ASE Certified Technician Generic: HO2S Heater Control Circuit Low (Bank 1 Sensor 2) Nissan: Heated oxygen sensor (HO2S) 2 Bank 1 - heater voltage low What does that mean? Heated Oxygen sensors (HO2S) are inputs used by the PCM (Powertrain Control Module) to determine oxygen content in the exhaust system. Bank 1, sensor 2 refers to the second sensor back on bank 1. The PCM uses the information gained from the Bank 1,2 HO2S mainly to monitor the efficiency of the catalytic converter. Integral to this sensor is a heater element The PCM controls this heater to warm up the sensor to operating temperature. This allows the engine to enter closed loop faster and reduces emissions on cold startup. The PCM continuously monitors the heater circuits for abnormal voltages or in some cases, even amperages. Depending on the make of vehicle, the Oxygen sensor heater is controlled one of two ways. One way is that 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. The other way would be 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 low voltage condition on the heater circuit, P0037 may set. Symptoms Symptoms of a P0037 DTC may include: Malfunction indicator lamp (MIL) illumination There will likely be no other symptoms Causes Potential causes of a P0037 trouble code may include: Bank 1,2 oxygen sensor heater element has failed Physical damage to heated oxygen sensor has occurred Control circuit (or voltage feed, depending on system) is shorted to ground PCM Oxygen sensor heater driver has failed === Possible Solutions== Do a visual inspection of the Bank 1,2 HO2S and wiring harness. If there is any damage to the sensor or any damage to the wiring, repair/replace as needed. Make sure wiring is routed away from exhaust. If all appears okay, unplug the Bank 1,2 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. Infinite resistance indicates an open in the heater. Replace the o2 sensor as necessary.

Hello, I'm getting a p0037 code. I have established it's one of the o2 sensores. Just trying to figure out exactly which one it is.


P0037 is for bank 1 sensor 2. Bank 1 is the leading bank where you will find cylinder #1. Sensor 2 is the downstream sensor, or the second sensor in that bank.

sensor two (downstream) is an O2 sensor that measures O2 content in the catalytic converter, it has no effect on drivability, but if the car runs well, you probably have some sort of exhaust leak before that sensor. If it runs bad, you may have a clogged cat. Also, check with a scanner that does Data reading to see if that sensor is basically giving the same readings, not varying millivolt readings from about .1 to .9 volts like the upstream sensors.

P0037. heater sen. where is it on the engine?


The code is for the heater in the O2 sensor bank one sensor two. That would be the sensor after the catalytic converter on bank one.
It could be the sensor itself or the power supply for the heater.

your truck should have four o2 sensors bank 1 sensor 1 is o2 sensor on cylinder 1 side before cat and bank1 sensor2 two is 02 sensor after cat banks 2 sensor1 is on other side berfore cat and bank2 sensor2 is after cat hope that helps when they read code it should tell you bank1 sensor1 or2 good luck

The engine light and VSC light are on (Vehicle Singapore 2004 Lexus RX 300. Diagnostics report Error code P0037


your o2 sensor is bad. vsc will go on for any small DTC displayed on the MIL (cel)

P0037 LEXUS P0037 LEXUS - Oxygen Sensor Heater Control Circuit Low Bank 1 Sensor 2 Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
Possible causes - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM) When is the code detected? The P0037 is set when the ECM detects an excessively low voltage through the heated oxygen sensor heater circuit P0037 LEXUS Description Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).

In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECMcontrols the heater element circuit by allowing current flow to ground.

The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.

Subaru wrx impreza showing fault code p0037. how do i fix this fault which sensor is it and where is the sensor located?


http://helpforcars.net/obd_codes/codes.php?code=P0037

It's an O2 sensor according to the above link, and it is bank 1 sensor 2 low, the 2 meaning that it is downstream past the catalytic converter but not on the manifold.

- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM) Possible Solution Tech Notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow, which is a very common problem for this type codes. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.
Good luck on this repair.

2004 altima 3.5L codes P0037 P0507 One is a heat O2 sensor how can you know which one exactly


P0037 HO2S Heater Control Circuit Low (Bank 1 Sensor 2)
P0507 Idle Control System RPM Higher Than Expected
bank 1 is the side with number 1 spark plug but the o2 sensor is going to be the one just before the catalytic convertor. the other codes has to with idle and you either have a vacuum leak (which would cause eratic idle(up/down))or you have no accelerator cable and there is a problem with one of the sensors either at the throttle body or on the pedal assembly.
