I think I narrowed it down to cylinder one. Below is a description of the code. The cel came on a mile away from the dealership, and they blamed it on the aftermarket coils. The problem I have with this is that I am not getting any other code. I also get horrible gas mileage ~14 mpg hwy and am wondering if the P1320 code is causing the P0135, P0141, P0155, and P0166 O2 heater codes. Maybe it is resting on a hot pipe, but that is a lot of circuits. Which O2 sensor did you change? Any one of the six coils could be causing the code so I recommend replacing all six at the same time.
I've also been chasing a P1320 which started soon after changing the spark plugs. The wiring harness can be removed by pressing in on the locking clip. Purchased 'BlueStreak' replacement coil, and installed it in 5. It also has a code P1320, P1705, and P0120. If circuit is okay, go to next step. Since money is tight, and what else is knew? Stop High fuel pressure is rare, the regulator should be tested but test the fuel rail no guessing allowed.
Aug 03, 2017 These engines had a lot of problems with coils, most people just end up replacing all of them. I have replaced the plugs, coils, and the crank position sensor. The work outlined requires testing equipment and anyone willing to work on their vehicle should have a minimum set: As far as testing goes: Spark tester Vacuum gauges, gas pressure gauges Timing light Multi meter Wire markers Compression tester Remote starter switch Feeler gauges flat and wire Tire pressure gauge Battery hydrometer Anti freeze hydrometer Battery charger able to charge at 3 rates, trickle, 10A and 50 A for equilization Doing the work is satisfying when done and done right, but it will cost you the tools, hand tools sometime the specific tool and testers and the longer that the keep a vehicle the more into it you will get. Measuring the resistance with the coil out of the vehicle may not show any failures, usually the coil fails under heavy conditions hard or certain temperatures. This is time consuming but cheaper.
Hi there, The nissan factory repair for the P1320 code is to replace all of the ignition coils. In the process, the valve cover gaskets can be. There is an overflow hose that is also clipped to the fan housing unlcip the hose and move it out of the way. Do this with each coil and see if there is one or more that is not firing. The problem is that I am due for emissions and due to the code, it will fail emissions.
This on-off operation induces the proper high voltage in the coil secondary circuit. You do sometimes get this code when the cam position sensor fails as well. You may find them a little cheaper online. Then from the engine to the body. My first cylinder coil would not fire at all however the rest of the coils were fine.
Once the alternator is free - you can get at the battery cable post and the other wires. While rotating the fan, bring the alternator around with it to the top and it will come out. Nov 22, 2013 I would say something cut into the wiring harness. You could buy one coil for the front bank and one for the rear and swap it between cylinders to see which coil is causing the code. They are a common failure item and all must be replaced at the same time along with the spark plugs.
It has been running rich, which may have caused the converters to fail. Guess what is wrong and you will be in the poor house, know what is wrong by investigating, testing, so that means money has to be spent renting or buying test equipment or using what you have to find the answer. Inside look for dirt, dust and clean, clean underside of cap. Now to figure out the 1320 issue. So I need to fix it. The owner is not good with cars so I am trying to help them out as they don't have much money to send it to a dealer.
I was expecting they have 1 code, but they gave me 3. All of the plugs were gapped correctly, and after each stab at a repair, the cel was cleared. There is a common fault on 2001 Nissan's that you can check; Lack of a non-resistive ground to the body. The stop in this write up is a section for you to perform the tests. When autozone first pulled the code, it said something that translated to a faulty part in the fuel tank Fuel Tank Pressure Sensor? See if you can take a tool get a better metal-to-metal electrical contact.
Thanks NissanTech for the diagnose reference. You should now have better visibility and access to the alternator. I replaced coil 1 on the first P0301 code. This has been an issue for a year, but it's time to get the truck emission tested soon. The O2 sensor was replaced almost 2 yrs ago. Sounds like either a bad module, or the computer signal reference signal or circuit? If that doesn't solve anything, try swapping it out with an adjacent ignition coil and see if the problem moves. Causes: — Faulty power transistor unit built into ignition — Ignition primary is open or shorted circuit to ignition coils — Ignition primary circuit poor electrical connection circuit to ignition coils — Faulty condenser — Crankshaft position sensor circuit Notes: The most common cause that will trigger the code is the ignition coils, one or more ignition coils may have failed.
Loosen the belt tensioner from below and remove the belt. If battery voltage exists, go to next step. This on-off operation induces the proper high voltage in the coil secondary circuit. Tech notes The most common cause that will trigger the P1320 code is the ignition coils, one or more ignition coils may have failed. With it running in open loop, could that cause the poor gas mileage? Make sure ignition coil 4 is completely plugged in.
