The solution is here : Nissan Frontier P0141 Possible Solution : Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. The other 2 are the ones that feed power and ground to it's heater. If your spark plugs look good, problems with your ignition system can also preventing a spark. They are independent publications and are not affiliated with or endorsed by or. Starter location and mounting detail-3. Knock sensors generally bolt into or thread into the engine block. Which is located above and away from the egr canister under the driver side rear bumper it is round and have about 3 hoses connected to it.
An interesting note though, Denso gave the the model number of a universal fit sensor that is manufactured at 15. How does a mechanic diagnose the P0141 code? Starter location and mounting detail-3. Your gas mileage will also be terrible, so you should try and fix it as soon as you can. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. Good luck finding whatever caused it in your Nissan Patrol. Check that the sensor cable or beam is not in contact with the exhaust system. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine.
The control module monitors how long it take the sensor to warm up and start sending an adequate signal. I hope to try that sooner than later. My trip permit runs out in 6 days! Apparently, Nissan has told them the resistance for both the upstream and downstream sensors are 5. First I tried a Bosch universal, then a Bosch Platinum original fit, then a Denso, and then finally another Denso. I jumped the sensor's two other wires to the plug and confirmed they were producing voltage both at the scan tool and with a multi meter. The relay also receives power on another terminal on the relay.
As for the cat, I'm pretty sure if it were shot I'd be getting an improper dataset in the scantool with regard to the downstream sensor's voltage produced. You'll be glad to know that your vehicle is equipped with an early warning system that could save you time, money, and fuel in addition to helping protect the car! If you understand how the systems were designed to work and how to test them, great! Hopefully the info can help someone in the future that experiences the same issue. Has any encountered anything like this before? I even took the last Denso to the bench, applied heat, and took a measurement. . For this test, go to.
You might also need the manufacturer and data systems that provide specifications and details relative to your specific model. This is not a part I just want to throw at the truck. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow. I just contacted Denso directly.
The P1320 refers to the ignition coil and wiring. Knock sensor indicates a knock coming from the engine, perhaps from cylinder 4. While not car-threatening, it's good to take care of this right away to improve gas mileage. It should not be considered a breakdown risk. Or aftermarket data systems such as , and others.
Please let me know if any of you have any ideas. P0141 Auto Trouble Code P0141 Auto Trouble Code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission. Took it back to the mechanic who tested the oxygen sensors and replaced one upstream with a universal one. There may also be other symptoms. If there is a way for you to check for the existence of such a bulletin, then that might save you a lot of time and money. They are presented in order somewhat of most to least likely to cause the problem.
So should installing a separate resistor within range, completely bypassing the sensor's heater element. To check for power and ground, you'll test the two indicated wires of the engine wiring harness sensor connector. Check the sensor, coil, and associated wiring. You should also check that the spark plug gap is set properly. To perform the job correctly you should look at the items that could have caused the reported failure of the sensor. If there is no fault in the heating element circuit, monitor the amperage of each heating element using the scan tool to determine if one of the heating element elements is causing the fuse to break.
That was 4 days ago. Technically, this hack should work. In a nutshell, all that's involved is making sure that the rear O2 sensor's heater element is getting power and ground, then verifying that it's resistance is within specification. Fortunately, everything you need everything you need to fix it right the first time is right here! The problem may appear only after a certain time of probe operation. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. I've got a really strange situation. The Terminator: It's in your nature to destroy yourselves.
P0141 Causes: Nissan Patrol Here are the most common issues that cause the P0141 code in the Nissan Patrol. The aftermarket data systems are available in our members only area by direct shipment from the distributor at great pricing. The P0325 description is knock sensor circuit malfunction and the P1320 is ignition signal - circuit malfunction. Only way to fix these 2 problems is replacement of the 2 components. Perform this test with a completely cold engine. The factory manual states that the measured resistance of the downstream oxygen sensor's heating element should be 11. .
