Lexus GX 2004-09 :: Fault Codes P0037 And P0057 - Oxygen Sensor Heater Control Circuit Low
May 10, 2012
What can be done regarding these faults? P0037 and P0057
Description:
Oxygen Sensor Heater Control Circuit Low (Bank 1, Sensor 2)
Oxygen Sensor Heater Control Circuit Low (Bank 2, Sensor 2)
The catalytic converters have been removed but the fault was present before that anyway. All I want is the VSC function to work again and the lights to go off. I have heard you can put dummy sensors in.

I recently had my Hyundai Entourage (2008) come up with the following engine codes: P0057 and P0037, both related to the downstream oxygen sensors. The generic description of the code is heated oxygen sensor heater control circuit low. As I understand this code, it is signaling that there is too much current passing through the heater circuit. The oxygen sensors test out OK for resistance, around 10 Ohms each and disconnecting them entirely and rerunning the test after driving a few times yields the same code. So I suspect the issue is not with the sensors but either the wiring or the ECU. I'd be a little surprised at a sudden short in the wires for both sensors but I suppose stranger things have happened. Oh and the fuse for the oxygen sensors has not blown. I am correct in reading these codes to mean there is an apparent short? Or are there any other things that could cause this to happen?

I have a 2010 Toyota Corolla 1.8L, the base model.
I recently had a check engine light, VSC off light (blinking) and traction control light come on. I took it to Autozone and had a p0037 code ring up for a new Bank 1 Sensor 2 oxygen sensor (downstream). I believe I have found the correct sensor (located under car, approximately near drivers seat) and it looks simple to replace, aside from the fact that the wires go through the car body.
Can confirm that I have located the correct sensor? And if so, what is the best way to get to where the wires connect?
Is it located under the drivers seat? What should I do about the rubber grommet located under the car where the wires appear to pass through?

P0032 Oxygen Sensor Heater Circuit High Voltage (Bank 1, Sensor 1)
I have read that in 2005 chrysler changed the ohms levels for the oxygen sensors and may need to have bcm reflashed to get a new oxygen sensor to work wheither its dealer item or not, is this true if i were to buy a mopar oxygen sensor? aftermarket is out of the question being the ohm readings would require me to spend some time at the dealer. is this code a defective sensor? or could it be related to the thermostat being faulty? am not low on antifreeze and temp gauge reads normal.

I have an emissions test coming up. I have 3 P codes that I'd like to eliminate before then. I don't want to "fix" the issues they are telling me about. Just make the codes go away. I know why they're there I just need to get rid of them.
What I have coming up is:
P0475 Exhaust Pressure Circuit Valve (result of EBPV delete)
P0541 Intake air heater A circuit low (result of aih delete)
P0640 Intake air heater control circuit (also result of aih delete)
What resistors I'll need and where to put them in?

SC430 came up with the check engine light, showing a "Oxygen Heater Circuit Malfunction", code P0155 (bank 2, sensor 1). Searching, I found out this is the oxygen sensor in the passenger side exhaust manifold.
My car is high mileage (over 130K), it's hard to justify purchasing a $230 sensor and paying for installation. My only goal is to keep the check engine light from turning on and passing state inspection/emission (the check engine light will prevent passing inspection/emission in my state).

My check engine light has came on and I received these error codes
PO441 : Evaporative emissions control system incorrect purge flow.
PO 455 : Evaporative emissions control system pressure leak-large leak.
PO 446 : Evaporative emissions control system vent control circuit fault.
Also only my driver side fan is working, may be separate issue?

I found the fault codes, I need the steps to fix them.
P0760 - Shift Solenoid,
CP0755 - Shift Solenoid
BP0340 - Camshaft piston sensor "A" Circuit
P0335 - Crankshaft Position Sensor A Circuit
I'd like to think it's as easy as replacing the sensors, but it never is.

I have a 1996 Ford Explorer Eddie Bauer Edition 5.0, the check engine light is on and my code reader gives P0161 and P0155 both stating that the O2 heater circuit sensor is bad. I replaced all 4 of the O2 sensors in the truck, cleared the codes but they still keep coming back. I have tried for a few days now to find something online similar to this but have had no luck. I am not sure what else to do.

I have some codes on my ranger 2000 here goes
P0141: o2 sensor heater circuit malfonction (bank 2 sensor 2 )
P0455: evaporative emission control system detected (large leak)
Now I will need to get that fixed cause I don't know where to look and what to look for ... For the leak I know there is a big crack on the plastic where the gas lid is could that be it ?

I bought my truck 2 month ago. I use it for commuting, only short trips now ( 10 min ). After about 2 weeks the Check Engine light came on. The truck is running fine, no problems I believe, starts easy. After another 2 weeks, the CEL disappeared. Another week, and the CEL came back on and it`s there since. I have a code reader, these are the codes and meanings according the manual:
P0299 - Turbocharger "A" underboost condition
P2286 - Injector control pressure sensor circuit high
P2287 - Injector control pressure sensor circuit intermittent
P0299 Pending - same as first but with "pending" status
This is my first diesel and my first turbo charged engine. Is this a common problem? How serious? It`s a bit strange that the error came up before but disappeared. Can that happen just because of the short trips I`m making? I`m planning a long trip soon with towing my trailer, so I want to make sure the truck will not break down during the ride.

I was plowing and when I put it in reverse it felt like it slipped, but then the dash message trans malfunction came up. I checked the codes and I got P0722 output shaft speed sensor.
Code P0720 (oss) sensor circuit fault
Then the truck went into safe mods. Is it just the sensor or is my reverse going out...

1999 Ranger 4x4 4.0 - P0135 O2 Sensor Heater Circuit (Bank 1 Sensor 1)
I have replaced the 02 Sensor, Passenger Side (Pre-Cat), with a Motorcraft DY831...
I reset the Check Engine fault codes, and took it out for a 50 mile journey... Check Engine light is back on, with the same exact code... What next?
I understand that it may be a fuse, and/or it may be a short in the wiring... Exactly how to test the wiring from the connector at the 02 Sensor all the way back to wherever I need to test?
I really need detailed directions, like wire colors, voltage required, or ohms, or whatever is included in this process...

Just started the truck after not running for a few weeks and drove around fine. Looked down and suddenly a CEL was indicated. Checked it with my Edge Evolution diagnostic mode and Code P0161 came up 2nd bank downstream heater circuit fault. I've also have an exhaust leak in the right passenger side exhaust manifold for about the last year. I've been waiting to install my newer 03' used engine when time and funds permit.

2 weeks ago a check engine light came on with P0351-Ignition Coil "A" Primary/Secondary Circuit Malfunction, took the car to Toyota dealer and replaced ignition coil for cylinder No1. I drove the car for about 10K and check engine light came on again with P0606-PCM Processor Fault.
For the past week I was monitoring the DTC's using INNOVA- CanOBD2 Code Reader 3030 (ordered ODB2 USB tool to check live data on a laptop, on it's way...). I had P0606 on all the time, about everyday. For 3 times I had P0157-O2 Sensor Circuit Low Voltage (Bank #2 Sensor #2) on.
What's the link between the two DTC's? Why not P0157 alone? Or P0606 alone? What is the procedure to diagnose this?

I have a 2000 motorhome on a f450 chasis. It has a V-10 with only two oxygen sensors up-stream from the catalytic converter. The monitors for the oxygen and oxygen heater sensors will not show "ready". I replaced both sensors and have driven it over 200 miles. They still show "not ready".

I've got a '99 Passat wagon with the 1.8T. My check engine light came on the other day. i had a friend check it w/ his OBD 2 code reader. I got 2 codes: 1300 & 1136. "boost calibration fault" & "fan circuit control malfunction" , respectively. are either of these worthy of a trip to the shop, or can i handle this on my own?
