SOURCE: dtc codes p0155 & p0051

I had the same problem and found out I was sold the wrong sensor, my 4.0 has four, they are all different, when you install a new sensor, you must make sure you clear the trouble code before you start the engine, ignition on engine off, that should do it, it worked for me, also if you have your own scanner and can erase the codes yourself, the wrong 02 sensor will turn engine light on with cold start, then after I erased the code it would stay off all day until the next cold start, thats when I found out my new 02 sensor was for bank 1 sensor 2, and not bank 2 sensor 1, hope this helps

SOURCE: Was told need to replace oxygen sensor (code PO150,PO400,and PO32

there are two sensors or more if it's a v 6 or v8 you have a post catalytic converter 02 sensor which is on the exhaust manifold and you have another after the catalytic converter they will be on the exhaust system in case your not sure what the exhaust system looks like, the 02 sensor looks like a spark plug it will have a quick disconnect that you have to unhook before you unscrew the sensor, 02 sensors will fail in three ways the heater burns out or the sensor gets lazy and does not cycle fast enough for the computer or gets fowled out by carbon and does not read at all, most of the time it's the sensor before the catalytic converter or on the exhaust manifold you will need to buy a special 02 sensor socket to remove it. It has a slot for the wires in it and will allow the socket to let the wires hang to one side the socket costa about $20.00 at any parts store if you have a schucks or autozone you can go there and ask them to test your car and it's free they can pull the code and tell you which one it is and point it out to you and you can buy the sensor from them once it is replaced the light will go off by itself, a heated 02 sensor costs on average $40.00 may be more or less not including sales tax.

Hi there, do you get water from the air conditioning unit entering the passenger foot well, if so then perhaps water is dripping onto the electrics below and causing these problems (blocked evaporator unit) alternatively, get jeep to reset your system (2 minute job) and this should work, keep an eye on it as the first new code that appears should be the problem area, hope this helps

What should I check with 3 codes P0051 , P0300, P1512 .its only car I have and I need expert advice what's smartest cheapest thing to do?


the following link is courtesy of obd codes .com the p0300 misfire code can be from the other to codes P0051 - Oxygen (A/F) Sensor Heater Control Circuit Low (Bank 2 Sensor 1) OBD-II Trouble Code Technical Description Generic: Oxygen (A/F) Sensor Heater Control Circuit Low (Bank 2 Sensor 1) Nissan: Heated oxygen sensor (HO2S) 1 Bank 2 - heater voltage low What does that mean? A P0051 DTC (diagnostic trouble code) refers to the O2 sensor (oxygen sensor) located on Bank 2 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2. This O2 sensor #1 may also be refered to as an air/fuel ratio sensor since on some vehicles it is. It detects the amount of oxygen in the exhaust gas compared to the outside air and then vehicle's computer adjusts the air/fuel ratio going into the engine. The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the A/F O2 sensor. Essentially this P0051 code means that the resistance of the heater circuit is lower than normal. In most cases, that resistance level must fall below 0.8 A to trigger the DTC code. Note, this code is very similar in nature to P0031, P0032, and P0052 Potential Symptoms Most likely you'll not notice any symptoms other than the MIL (malfunction indicator lamp, a.k.a. the check engine light) will illuminate. Causes A P0051 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 Possible Solutions To fix a P0051 DTC code, you'll need to do a proper diagnosis. To do that, you'll want to inspect the wiring and connectors leading to the sensor. Also if equipped with a heater relay and fuse, you'll want to check those as well. Use a digital volt ohm meter to: check for 12 volts at the heater circuit feed (hint: unplug the sensor and check at the wiring connector to do this measurement) check the ground circuit for continuity measure the resistance of the heater circuit (done on the sensor itself) measure the resistance and voltage of the wiring Refer to a service manual for the correct specifications (volts, ohms) for your vehicle. On some Toyota vehicles this code is triggered when the resistance of the heater circuit is below 0.8 A. With that said, a common fix for this DTC is to replace the air/fuel (O2 oxygen) sensor #1 on bank 2 (the side of the engine that doesn't contain cylinder #1). Please keep in mind that OEM (original equipment) replacement sensors are recommended (from the dealer). Aftermarket sensors can be less reliable and of poorer quality (not always, but more often). There's also a chance that replacement parts for the P0051 code may also fall under a federal emissions warranty (check with your dealer to see if it's covered).

Copyright OBD-Codes.com OBD Codes Your OBD-II Trouble Codes Repair Site Home Trouble Codes FAQs Forums Store P0300 Diagnostic Code - Random Misfire Technical Description Random/Multiple Cylinder Misfire Detected What does that mean? Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly. A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why. Symptoms Symptoms may include: the engine may be harder to start the engine may stumble / stumble, and/or hesitate other symptoms may also be present Causes A code P0300 may mean that one or more of the following has happened: Faulty spark plugs or wires Faulty coil (pack) Faulty oxygen sensor(s) Faulty fuel injector(s) Burned exhaust valve Faulty catalytic converter(s) Stuck/blocked/leaking EGR valve / passages Faulty camshaft position sensor Defective computer Possible Solutions If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back. If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors. Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open. It is helpful to have access to a factory service manual and an advanced scan tool to properly diagnose a random misfire DTC. P0300 Diagnostics Video Here is a helpful video that may assist you in learning more, diagnosing, and repairing your P0300 DTC. This video is intended for auto repair professionals but could be helpful to DIYers. It shows use of an advanced OBD-II scan tool during diagnostic steps:

2007 Toyota sienna V6 P2197 code from Autozone diagnostic.


Solved. I have 2008 Sienna with Check Engine and VSC lights on. Scanned codes were P0051 and P2197. Oxygen Sensor Bank 2 Sensor 1 needs to be replaced. You can see this sensor on the right side of the engine when you open up the hood. You need to get an Oxygen Sensor socket (I used Tekton 7/8in 22mm which costs $9) and a wrench extension to reach it. Spraying liquid wrench a few times on the base of the old sensor also helped to loose it. The replacement sensor I used was Denso 234-9049 which costs $85 from eBay. Lights went off after the sensor was replaced. It took me 30 minutes to replace.

Which senser needs replacing with code p0051


A P0051 DTC (diagnostic trouble code) refers to the O2 sensor (oxygen sensor) located on Bank 2 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2.

This O2 sensor #1 may also be refered to as an air/fuel ratio sensor since on some vehicles it is. It detects the amount of oxygen in the exhaust gas compared to the outside air and then vehicle's computer adjusts the air/fuel ratio going into the engine. The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the A/F O2 sensor. Essentially this P0051 code means that the resistance of the heater circuit is lower than normal. In most cases, that resistance level must fall below 0.8 A to trigger the DTC code.

Potential Symptoms Most likely you'll not notice any symptoms other than the MIL (malfunction indicator lamp, a.k.a. the check engine light) will illuminate.
Causes A P0051 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
Possible Solutions To fix a P0051 DTC code, you'll need to do a proper diagnosis. To do that, you'll want to inspect the wiring and connectors leading to the sensor. Also if equipped with a heater relay and fuse, you'll want to check those as well. Use a digital volt ohm meter to:
  • check for 12 volts at the heater circuit feed (hint: unplug the sensor and check at the wiring connector to do this measurement)
  • check the ground circuit for continuity
  • measure the resistance of the heater circuit (done on the sensor itself)
  • measure the resistance and voltage of the wiring
Refer to a service manual for the correct specifications (volts, ohms) for your vehicle. On some Toyota vehicles this code is triggered when the resistance of the heater circuit is below 0.8 A.
With that said, a common fix for this DTC is to replace the air/fuel (O2 oxygen) sensor #1 on bank
2 (the side of the engine that doesn't contain cylinder #1).

Please keep in mind that OEM (original equipment) replacement sensors are recommended (from the dealer). Aftermarket sensors can be less reliable and of poorer quality (not always, but more often). There's also a chance that replacement parts for the P0051 code may also fall under a federal emissions warranty (check with your dealer to see if it's covered).
