SOURCE: I have a 1999 oldsmobile

fuel pressure regulator on the fuel rail is probably it or the egr valve is stuck open allowing burnt fuel to flood the intake, im leaning towards the fuel pressure regulator because the o2sensor is probably reading rich or if its reading lean then i would choose the egr valve . good luck

SOURCE: 1999 pontiac grand prix . will not run

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

SOURCE: Cleaning the Mass Air Flow Sensor

i will try to help. 171/174 indicates lean condition in engine. the mass air flow sensor is located in the rubber tube going to throttlebody. you can try to clean it. using mild carb cleaner safe for sensors, remove sensor from tube. spray clean the tiny wires located in the cylinder. do not touch them, they are very delicate. these engines are also notorious for leaking intake gaskets and faulty pcv valves. these will all set these 2 codes. feel free with anymore questions.

SOURCE: CODE PO102 after Mass Air Flow Sensor replaced

Most faultcodes don't disappear automaticly, the have to be 'reset' manually after repairing. It sounds like the code didn't get erased after replacing the MAF. You could try to disconnect the battery for 10 minutes (disconnect and reconnect the negative (-) pole), which should erase the code.

Whenever the engine light still comes back on after that, there probably still is some (other) problem ...

SOURCE: I have a 2005 Chrysler Town & Country with

there are no codes that say replace O2 sensors,or remove converter,Thats just somebody's guessing,When it says O2 sensor that tells the mechanic to look for trouble in that area,wiring or faulty readings,And there are four O2 sensors.

Code p0420 acura m'dx


1996-newer (OBD-II) vehicles use oxygen sensors and a catalytic converter to reduce emissions. There is one O2 (oxygen) sensor in front of the catalytic converter (called upstream), and one behind it (downstream). When the engine is warmed up and running normally the upstream oxygen sensor reading fluctuates and the downstream one is fairly steady. In the case where both readings are fairly steady, a P0420 check engine light code is set.
Possible Causes: Oxygen (O2) sensor not working correctly
Damaged or leaking exhuast (pipe, manifold, catalytic converter)
Damaged catalytic converter
Diagnostic Help:
To diagnose a P0420 trouble code we begin by checking for exhaust leaks under the vehicle. Then use an oscilliscope to check the waveforms of both upstream and downstream O2 sensors. The front reading should vary, the rear should be steady. Replace as necessary. Check the rear Heated O2 Sensor. Check the catalytic converter, replace if necessary. If necessary, check for wiring and component concerns. See our article "Automotive Circuit Testing 101", if you need more assistance with this. Remember to refer to an model-specific repair manual for proper instruction.

I have an 03 Camry 4cyl LE that needs an O2 sensor. Does this model have more than one sensor? I have gotten conflicting info about the number of sensors and corresponding pns.


YOU HAVE 2 OXYGEN SENSOR UPSTREAM OXYGEN LOCATED ON THE EXHAUST MANIFOLD. THE DOWN STREAM OXYGEN SENSOR LOCATED BEHIND THE CATALYTIC CONVERTER.YOU CAR HAS ONLY 2 OXYGEN SENSORS.

Were is upstream 02 sensor on an 2002 toyota camry.


The secondary oxygen sensor is typically located behind the catalytic converter somewhere on the exhaust. You will need to get under the vehicle to look for it. it should have wires coming out of it leading up to the engine bay. It should be fairly easy to replace. It screws in just like a spark plug

B1S1 means first (upstream) , closest sensor to cyl. head , usualy at exhaust manifold.Bank 1 is cyl. head with cyl.#1 if you have V6 engine.
Best choice for brand - Denso.

I have a 2002 toyota camry V6 and did not pass


O2 sensors are a possible cause. It has one converter, but 2 oxygen sensors...1 upstream, and 1 downstream of the converter. Which means one is very easy to get to (under the hood, on the manifold), and one is not. Usually the check engine light will come on if O2 sensors are faulty.
