Niether t … he cam or crank sensors have any adjustments. The sensor that is most likely causeing the problem is the low oil pressure sensor. First, rule of thumb says not to use aftermarket for electrical parts and it's been proven over and over again that they either fail right off or don't last. A P0302 code, for example, would tell you cylinder number two is misfiring. Once the carb spray hits the engine cylinders, you'll get an instant Rich Condition which will make the O2 sensor respond by producing its maximum voltage 0.
I have spent alot of money only to hit another dead end. Also, if anyone has fooled with the wiring to the sensors, some have cooling tubes which are embedded in the wiring. 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. I would suggest spark plugs, spark plug wires, distributor cap, and rotor if applicable. But it sounds like it is probably got some gunk in it. I curb the car twice, damaging my tires once, so as to not hit other drivers.
You should see 12v when the engine is cold. Sometimes it would stay on for days. Ashley answered 9 years ago When do you refuel? That should reset the computer and get rid of any stored codes. Just recently I took the car in again to massey-yardley for poor gas mileage and the same power problem, this time with a check engine light active, in Nov of 2007, the dealership said it was a bad instrument cluster and a bad oxygen sensor, which they replaced. Precision-manufactured with a sensing element incorporating premier technical ceramics Optimizes emissions and fuel economy when replacing worn oxygen sensors. The dealership also said since I'm not happy with the results I should go to another dealership to have it looked at! But then, got the car back, no check engine light on first drive, stopped somewhere for 5 minutes, get back in, start it again, check engine light back on. Have parts delivered straight to your home, or find the nearest Advance Auto Parts store to check out our Oxygen Sensor stock in-person! If you smell rotten eggs in the exhaust, your cat converter needs to be replaced.
Did you remove the negative battery cable for 5 minutes, step on the brake peddle and them put it all back together? I have had several near misses with other vehicles on the roads. If so that is not good for your car. In some cases, the catalytic converter has gone bad. There is either a part failure or it is miss installed. On some Toyota vehicles this code is triggered when the resistance of the heater circuit is below 0. The speedometer, the tachometer, the gas gauge all go to zero. I first brought it to the dealer and they replaced one of the sensors.
Hello all :- I recently rebuilt the engine and turbo in a 2004 cruiser for a friend and now I cannot get the check engine light to go off. This has been happening for over a year now. Anyway…perhaps there is more info from what shops have done that would make sense out of why a P0304 has been dealt with the way it has. Please confirm the correct part before ordering and if the connector does not match, do not install. That being said, I used Bosch 02 sensors for both when I replaced them for pre-ventative maintenance and they have been in they for about 21,000 miles without a problem. In most cases, that resistance level must fall below 0.
With the computer engine lite causing this problem Chrysler should have a recall on it. Please help myself and other pt drivers having the same problem. Random misfires that jump around from one cylinder to another read: P030x codes also will set a P0300 code. From overall sensor design to the critical ceramic element, Bosch is known worldwide for quality and performance. There's also a chance that replacement parts for the P0031 code may also fall under a federal emissions warranty check with your dealer to see if it's covered. I would suggest spark plugs, spark plug wires, distributor cap, and rotor if applicable. To do that, you'll want to inspect the wiring and connectors leading to the sensor.
Walker Oxygen Sensors are precision made for outstanding performance and manufactured to meet and exceed all original equipment specification and test requirements. Aftermarket sensors can be less reliable and of poorer quality not always, but more often. I doubt it's the sensor s themselves. Did you remove the negative battery cable for 5 minutes, step on the brake peddle and them put it all back together? 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. Ho2S 2 signal is less active than signal produced by front oxygen sensor. This article will show you how to test the upstream oxygen sensor O2S11 on your 2.
I'm going to do that but it's hard when you have to work! The code is for the preheater, not the sensor itself. Yes I have cleared the codes. I hope my solution is helpful, perhaps a Chrysler mechanic will answer you. It is not impossible that the sensors you purchased could be bad. When it malfunctions, it sends false data to the engine management computer which then adds too much fuel into the engine.
Jun 29, 2011 P0300 is Basically this means that the the computer has detected that not all of the engine's cylinders are firing properly. Hi my name is kyle and I have an 05 pt cruiser stock and I have had problems with the o2 sensors since the first few months. I doubt it's the sensor s themselves. P0304 misfire code came up in diagnostics again and again. Have a nice weekend and thanks for using FixYa.
To do that, you'll want to inspect the wiring and connectors leading to the sensor. I have checked the ground circuit for the sensors and it checks out fine. 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. No matter the situation, Advance Auto Parts has the Oxygen Sensor product you desperately need. Otherwise, check the coils a. Installation Notes: Vehicles equipped with Air Fuel Ratio Sensors may look very similar to the Oxygen Sensor. Essentially this P0032 code means that the resistance of the heater circuit is higher than normal.
