Ford - Explorer :: Check Engine Light Is On For Codes P0161 And P0155 - O2 Heater Circuit Sensor Is Bad
Apr 24, 2014
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 a 2002 Jetta 1.8t. My check engine light came on and it gave me the code P0135 sensor heater circuit. Bank 1 Sensor 1. We bought a new 02 sensor and replaced it. We definitely bought the right one too. Cleared the codes. After a little driving the CEL came back on with the same code P0135. What is wrong and how I can fix this?

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.

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).

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've owned my 2012 F-250, 6.7L for less than a week and it has a check engine light. The local dealer can't see me for a week, and I need to leave town next week.
I went to AutoZone to have the codes checked and this is what they came back with:
P2033
Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2
P2031
Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2
Can I drive on these codes, or should I park the truck until Ford can see me?

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?

I cleaned my k&n air filter on my 02 passat 1.8 turbo let it dry oiled it very lightly, and 50 miles later I get a check engine light on, pulled the code 16486 and it says Mass or Volume Air Flow Circ Low Input. Cleared the code put a frame in until I can get it filter. Why that would throw me that code, k&n oil gumming up my sensor??

My 1998 Explorer with 120,000 mile on it. The check light just came on. I have had several auto part stores plug in the scan tool and there were no error codes. I'm looking for the reset button location. I am also wondering should there be something missed by the scan tools, will the light activate should there be a real problem.

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...

1996 Ford Explorer on a small island with no mechanics. Vehicle does less than 100 miles per year, never over 20 mph. The check engine light came on and the code reader says it's a problem with the Camshaft Position Sensor. The vehicle runs fine, just as it did before the check engine light came on. I'm tempted to put some electrical tape over the check engine light and keep driving.

1997 2wd, 4.0 - As you can guess it runs pretty bad at idle. It has O2 heater circuit codes for all 3 sensors. I'm leaning towards the ECM because the 2 heater wires are both hot with the key on. I unplugged the computer and turned the key on and just one wire is hot. Looks like the ecm is supposed to ground the wire to turn the heater on, but it's going hot instead?

Engine light came on yesterday and started missing on take offs. Giving code p2285 Injector Control Pressure Sensor Circuit Low. I've done the research and understand the problem. It's the weekend and shops closed until Monday. Is it safe to drive in the mean time? Is there any risk of doing damage? What's the risk of it quitting or failing start in the short term, today?

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 ?

2004 Sport Trac V6. Been having hard shifting and P0715: Input/Turbine Speed Sensor Circuit. Cleared the codes and still returns.
From my searches, readings and looking at the parts diagram. On the newer 5 speeds the sensor is the one on the inside of the tranny. This requires taking the entire tranny apart? Is there an external connector for the sensor that I can check or clean first? Replace this sensor. I know the older ones were mounted on top of the tranny. I think this one is mounted on the inside though.

I have a 2007 f-250 6.0 liter turbo diesel. I was pulling a trailer with a golf kart on it and was not in tow haul. I was going up a hill and it shot up into 5th gear. I pulled into my house and shut it off and refired it and it acted fine. I went on a little test drive to see if it was going to do it again before I went on my trip. As soon as it shifted into third gear the tow haul light started to flash on my dash and went to 5th gear and would not down shift even if I did it on the column.
I scanned the truck with my snap on modus and it gave me these codes. P0706-transmission range sensor A circuit range/performance, P0707-transmission range sensor A circuit low input, and P1702-transmission range sensor circuit intermittent. I put a transmission harness in it and started it up and it ran fine and the codes were gone. I went for a test drive around the neighborhood and as soon as it hit 3rd gear it did the same thing as before. Today I put the old one back in and checked the codes so I could write them down and there weren't any so I went for a drive and it shifted through all the gears great and downshifted fine as well.
I pulled into my drive way to check for codes once again and there weren't any. I was gonna go for a ride in tow haul to see if it would do it and as soon I put the truck in reverse it started to idle high and the tow haul light started to flash again. I put it in drive to pull back into my drive way and it immediately shifted into 5th gear and threw the same codes...

CEL/OBDII code P0141 - O2 Sensor Heater Circuit Malfunction
So I just bought this car 64k well maintained but cant get rid of the check engine light. Replaced downstream O2 sensor with no luck. As soon as I get home I'll check voltage @ connector. Lets test the O2 sensor connection and test the pins to make sure there is no break in the wires.

2001 F250. I have had issues on other trucks where you get a funny-acting speedometer with a code that comes up as VSS (sensor on top of the rear differential)....And it shifted exact same way.
My new truck speedometer is totally fine and the ABS is on with codes:
C1158 Left front speed sensor coherency malfunction
C1155 Left front speed sensor input circuit malfunction
Shifts about the same way on the trucks with bad VSS.
Question is will a bad front speed sensor affect the way the trans shifts? Doesn't happen all the time. If you go slow it shifts smooth. If you pull off fast a barely noticeable jerk from 1-2 and 2-3....
