Question about 2001 Ferrari 360

3 Answers

Misfire on etithe bank and 02 senr 1 bank 1 high also open loop problem

I'm working on this 01 ferrari 360 and had to replace bank 1 snr 1 because it was not goin to close loop, after that the w\car run good for a couple of days but this morning i had history codes for misfire on 123 and 4
and also bank 1 snr 1 to high code,
the main problem is every time i drive this car for 10 to 15 miles start giving
codes for high o2 snr or misfire on lt or rt bank,
but when i drive it the rt rr 02 snr seems to keep at 75 to 85 mv
while the other lt rr keeps arrown 750 to 800
any idea what the problem will be? also when this car start acumulating multiple codes then it will loose pwr,
the fuel system pressure is about 52 psi on both banks and the fuel trims
seems to be ok, but some times either the rt or lt banks stay on open loop and the scaner reads fail. on the loop monitoring data line.

    i was tinking about trying that, but i don't know this cars very well and don't know if by unpluging the battery, it will activate any antitheft system and then have a won't start problem, do you know if they have that system? or the radio might have a code after doing that? because the mercedes ml 320 wil not start after replacing the battery. thank you. and let me know

  • fernando arevalo May 28, 2008

    thank you very much for the opinion i will try that but that's the last part i will try since i charge 8 hr for this car allready, and i'm fixing this for an auto repair, but you might be rt.

  • fernando arevalo May 30, 2008

    acording to my customer they took this car to a ferrari dealer and they could not fix it
    i'm not sure if is true or false but that's what they say
    the only problem is than this car runs good for a couple of days but sometimes gets codes for misfire iather on bank 1 or bank 2
    nad also gett the code for 02 sensor 1 bank 1 too high and then start runing very bad

  • fernando arevalo May 30, 2008

    2001 ferrari 360 geting codes from bank 1 or sometimes bank 2 misfiring also po300
    and after clearing codes and drive it for like 12 miles it reads bank 1 sensor 1 high
    and also the data in teh scan tool is reading like 75 to 95 milivolt on the rt rr 02 sensor and like 750 on the lt rear o2 sensor

  • fernando arevalo May 31, 2008

    i will try your sugetions and thank you for that but the wear thing on htis car is than i either get one bank misfiring or other bank misfiring never show both banks or cylinder from both banks misfiring is either bank one or 2 and other thing what bithers me is than also the firts code to apear is ban1 snr 1 high and i repace the sensor twice
    this car has a coil on plug sytem but i will try your sugestions all what i have to do is wait for 2 rear 02 sensors than had been order and wait for my friend to call me to take a look

  • fernando arevalo Jun 01, 2008

    i will try to talk to ferrari to see if they can give me any advise thank you.

Random misfires that jump around from one cylinder to another may also be caused by a lean fuel condition or a weak spark. The challenge here is figuring out what is upsetting the fuel mixture or robbing the spark. The underlying cause is often a vacuum leak in the intake manifold or one behind the throttle body that allows unmetered air to bypass the air flow sensor. A lean misfire can also be caused by an EGR valve that is jammed open or is not fully closing.
But i think it may be a simple problem caused by bad or loose wire connections. Make sure all wiring connections involving at ignition circuit are good.

    Hello Lasvegastech:

    If it is get the codes out of the computer Misfire codes range from
    P0300
    for random or multiple cylinders and continue up P0301 for cyl 1 to
    P0306 for cyl # 6. That code will tell you what cylinder. Most misfires
    on Vortecs are from plug wires

    if the computer cant do calculations based on known good component sensors then the logical conclusion is a damaged computer, have you talked to ferrari about this? they may have faulty components out here in the real world

I have a 2012 camry se that has a rough idle


NO CHECK engine lamp (CEL) glowing running???????
which engine, there are more than one engines, offered on most cars.
that is misfire. and misfire is complex.
there are 50 causes of misfire, on Otto cycle engines (gas)
http://www.fixkick.com/misfiring.html

and more if flooding.
hot or cold engine?
or both?
ever do the 60k tune up?
id bet the engine is good, so we can remove 1 of the 3 main causes.
1: bad engine , no
2: bad spark, id bet not if miles is low, is it? below 60k?
3: bad fueling.
that is the proper order,
so if car is tuned up and spark is good.
then it must be fueling. so we connect the scan tool (any Can-bus)
and see DTC errors and it MIL active.
ok its sees misfire P0300s?
if no errors and its misfiring.
we then look at all sensors live with the scan tool.
id bet the engine dont hold closed loop hot, idle , as it must.
screen says, CL = active, or like kind.
if v6, there are 2 banks that must be in closed loop status.
I'll stop here, but will say I have a battery of tests for CL failures.

one is to make sure the 02 sensors work right and that there
are no exhaust manifold cracks near any 02 sensor.
i try to force the engine leaner and righter (tricks) that might
wake up a dead 02,
to see if it swings. (called cross counts)
the causes are many if the sensors are good.
fuel pressure out of spec,
injectors bad, leaking or clogged.
bad fuel.
dirty MAF sensor.
ECT stuck at wrong temperature for any reason, 180F or more is good.
and more... ask.

Cylinder misfire spark


how many miles on the odometer, mines 95k.
ah a v6, P0306 is #6 misfiring. 2.5L V6
300 is all 6 misfiring.... oops.
it is. for sure.
misfire is cause by many things, only 3 in physics, but many real world. (compression + spark +fuel rates)
i works this easy, way.
i have a full scan tool not just a code reader (near useless it)
i make sure my V6 (I have an 04) holds closed loop at idle and 2500 rpm. i f not , fix that first.
easy, it is. just look, bingo, Open loop, (out of control)
fueling is out of control.
but, first i do that tune up. in the manual, 60k , 120k, 180k, see?
do that first. , spark plugs dont last foreever nor filters.
then i replace both front 02 sensors at 100k miles. there design life.
V6 has 2 front sensors. (rear can , just sit and be ignored)
if it misfires. now, i toss a coin.
compression or fuel pressure.
i can do both in 30min flat but i toss coin lands on fuel.
i check fuel pressure and its.
60psi, fuel regulator is bad,
20psi, same, or bad pump or bad 12vdc to pump, 8v to pump is bad wiring.
one thing that helps is to find out if the engine is running too rich or too lean.
and if there are cracks in the exhuast near the 02 sensors.
i force the EFI rich and lean watching both 02 sensors in my scan tool
to see if i can force them lean or rich.
on the v6, we can introduce air leaks, to the plenum.
this will cause lean, and the o2 most react to my lean forcing
or its dead.
i can force richer, if i suspect lean or 02 shows lean, by
removing the Fuel pump regulator hose (vac) and plugging hose fast.
this causes the FPreg to go to high pressure. max.
causing RICH>
i watch the 02 and see it go rich, if not the 02 is bad or you have exhaust leaks, or dead cylinder causing the 02 to fib.
you have 2 banks, and both banks are running off 1 MAF
so you can look at both 02 sensors (front) B1S1 and B1S2
and see if both react the same. to my forcing's.

i dont think you have 3 bad cops out 6. no.
if any cylinder misfires on bank one, then bank 1 o2 goes nuts
same with the Bank 2. this can aid troubleshooting having 2 banks.
the MAF can not lie for 1 cyclinder nor one bank
the 02s can lie for each bank,
both are key to diagnosis.
let me give an example say
injector 1 leaks.
causing 301s
v6
246
135 left
this is your lay out.
my guess is its not lost compression (no test guess, mostly useless)
not 2 bad cops one on each side will cause 300s
not one bad cop. as other side would be ok.
not one bad injector.
my guess, is fuel pressure is way off.
but///???
or maf running lean (dirty, spary clean it 12inches away not close)
low fuel pressure
too high fuel pressure.

all comments are for engine with 60k mile service done,
60k, 12ok, etc.

As of 1996,all cars sold in the US were required to have an OBD-II computer interface port.
You may want to go to Advance Auto Parts, AutoZone, or Pep Boys, and get a free read
of the code(s) that you computer may be posting to help with your diagnosis.

The code coming from your vehicle's computer may be one or more of:


P0130 02 Sensor Circuit Malfunction (Bank I Sensor 1)
P0131 02 Sensor Circuit Low Voltage (Bank I Sensor I)
P0132 02 Sensor Circuit High Voltage (Bank I Sensor 1)

Maximas with the VE30DE and VQ30DE engines use a distributorless ignition system that is controlled by the Engine Control Module (ECM). The ECM receives a signal from the crankshaft sensor (the CPS - Crankshaft Position Sensor), and processes the signal based on inputs
from other various engine sensors, including the Oxygen sensor.
(this is the role of the O2 sensor in ECM operation).
Then the ECM sends signals to each of the individual coils in the proper firing order.
This system is more efficient than a distributor, and has fewer moving parts. The high voltage coils are directly attached to each spark plug, allowing a higher energy spark within the cylinder. A high energy spark means a faster, more thorough burning of the air/fuel mixture, which produces more power and lower emissions.


SECONDARY SPARK TEST - works for all cars, including Maxima.


1. Remove the spark plug.

2. Install the spark plug to the ignition coil/coil pack, then attach the coil wiring.

3. Ground the plug at a good ground location on the engine.

4. Crank the engine and check for spark.

5. If spark occurs, the ignition system is functioning properly.

6. If no spark exists, test the ignition coil/coil pack, power transistor and related wiring.

----------------------------------------------------------------------------------------------------------------------------
HEI Ignition Spark test - works for all cars, including Maxima.

The next level test you may want to try is a HEI (high energy ignition) spark tester kit. Cost is
about $30 at most auto parts stores. Harbor Freight Tools sells a chinese equivalent for about $16.
Place the spark tester on each of the spark plugs, and watch as the little light in the tester will
light up each time the spark plug is fired by the computer. You can actually see weak or
intermittent sparking as the motor runs - you can tell by the relative strength of the light as
you compare the intensity and duration of the light across all 6 cylinders.

If your problem were the alternator (or its built-in voltage regulator), your battery would not be
getting a proper charge, and you
wouldn't be able to start the car after a drive, since the battery would have been drained during the
drive - normally, the alternator will both charge the battery and run all electrical
features of the car during a drive.

To test your alternator, place your DMM (digital multimeter) across the battery terminals while the
car is running - it should read 13.5VDC to 14.5VDC. With the car off, you can test your battery
voltage with the same DMM - it should read 12.65 VDC (for a fully charged battery).

Alternatively, you can take your car to Advance Auto Parts, AutoZone, or Pep Boys, and they'll
attach their "charging system tester" to your car and give your car a nice test for free.
I do this with my customers' cars just to get that nifty printout of the problem. Its nice
to show a vehicle owner somethng in black & white when I'm recommending a new charging
or ignition system component (some of which can be a bit pricey).

Being a V8 you obviously have one cat converter to serve per cylinder bank, you also have one 02 sensor and one pyrometer per cat converter, that slow down signal could have several meanings, either you have a faulty pyrometer or 02 sensor, a damaged cat conveter or even a fouled spark plug, best thing to do is have it put on a scanner and see what fault code comes up.
