Ohm specs for 2009 altima please!!

[gingi801]

Hello, I have been running in to some electrical problems lately with my car and I have always hated to be that guy to just ask with out lookng . but I have looked and have not found any sort of ohm specs for the electrical components of the 2009 Nissan altima s2.5l. Please help me

dear
which sensor or solenoid you want to now its ohm?? do you have specific one? or you want all. if you want all sensors and actuators specs you can find them on the service manual electric section:

EC section
every thing is over there

thank you for the resource of information. so I looked through until I reached the ignition coil diagnosis and I am very confused it says that the ohms should be at 0 am I reading the right ohms from the chart? cause I have never seen a coil have 0 ohms

Thanks for the reply,
In the FSM it says to test by checking each terminal however it doesnt say the exact spects of ohms that it should be at. Is that "ehow" article accurate to our cars even though it doesnt follow the same procedure of finding the ohms?

Follow the troubleshooting steps in the FSM

OK I will. In the table on page EC 470 the ohm diagnosis says "except" (0 and infinity)
What does it mean? I've never seen that type of spec.

You are testing for continuity or a possible open in the coil windings with the use of a multimeter

See page EC 473
.
CHECK IGNITION COIL WITH POWER TRANSISTOR-II
CAUTION:
Do the following procedure in
the place where ventilation is
good without the combustible.
1. Turn ignition switch OFF.
2. Reconnect all harness connectors disconnected.
3. Remove fuel pump fuse in IPDM E/R to release fuel pressure.
NOTE:
Do not use CONSULT-III to release fuel pressure, or
fuel pressure applies again during the following pro-
cedure.
4. Start engine.
5. After engine stalls, crank it two or three times to release all fuel pressure.
6. Turn ignition switch OFF.
7. Remove all ignition coil harness connectors to avoid the electrical discharge from the ignition coils.
8. Remove ignition coil and spark plug of the cylinder to be checked.
9. Crank engine for 5 seconds or more to remove combustion gas in the cylinder.
10. Connect spark plug and harness connector to ignition coil.
11. Fix ignition coil using a rope etc. with gap of 13 - 17 mm (0.52 -
0.66 in) between the edge of the spark plug and grounded metal
portion as shown in the figure.
12. Crank engine for about three seconds, and check whether spark
is generated between the spark plug and the grounded metal
portion.
CAUTION:
• Do not approach to the spar
k plug and the ignition coil
within 50 cm (19.7 in). Be car
eful not to get an electrical
shock while checking, becau
se the electrical discharge
voltage becomes 20kV or more.
• It might cause to damage the igni
tion coil if the gap of more than 17 mm (0.66 in) is taken.

Ohh OK I understand why it says 0-infinity. What should be a healthy ohms on the coil?
