I have done some research on these and have found whats what. Id like any info on part numbers and things to be concerned with. The maxima is my wifes car and we need to get it back to a ok.

Pulled codes
c1109-battery voltage abnormal- Cause/fix ?
p1800-vias control solenoid valve- we did a block off a few yrs back. Maybe i did something wrong? I still have the valve and canister installed. should I have done something else or diff?
p0340- cam position censor bank 1 part #? I looked on rockauto and its left or right not banks.
po159 & p1167- same sensor part #
po139 & p1147-same sensor part #
poo21- ?


Anyhelp would be appreciated

 

Interesting list. The C1109 is a new one to me and I couldn't find anything definitive on it. This is what I found the most times.

C1109 - ABS actuator and electric unit (control unit) power voltage is too low.
Could be caused by malfunctioning alternator.
could be caused by running different sized tires?

Have the charging system and battery checked out. Then there is that part about having a mixture of different sized tires. And I suppose that it could also be the ABS unit itself.

The next thing is Nissan terminology vs the rest of the world, or bank 1 and bank 2.
Because the engine is transverse mounted, they don't use the term left and right. The translation is bank 1 equals the right bank, bank 2 equals the left bank.
Bank one is next to the firewall and has cylinders 1, 3 and 5.
Bank 2 is next to the radiator and has cylinders 2, 4 and 6.

P0139 O2 sensor bank 1 sensor 2 slow response
P1147 O2 sensor bank 1 sensor 2 not sending proper voltage

P0159 O2 sensor bank 2 sensor 2 slow response
P1167 O2 sensor bank 2 sensor 2 not sending proper voltage

More translation - the engine has 4 oxygen sensors - Bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1, bank 2 sensor 2. Sensor 1 is located at the outlet of the exhaust manifold. The parts stores will call this the upstream sensor. Sensor 2 is located after the pre-cat and parts stores call this the downstream sensor. In the 5th gen stickies, there is "5th Gen General Information, Maintenance, and Common Issues". Click on this link and page down about 3 screens to a diagram of the exhaust system and the O2 sensors. Following the diagram is a list of all the check engine codes that you could get for the O2 sensors.

P0021 IVT control bank 2 - IVT means Intake Valve Control. The IVT solenoid is not advancing or retarding the camshaft like it should. It uses oil pressure to accomplish this, so it could be sludged up and might be cleanable. But it also has a solenoid in it and maybe the solenoid is bad. But it is also possible that the camshaft sensor for that bank is causing the error, but the IVT solenoid is more likely the problem. Nissan part # 23796-EA21B.

P0340 - camshaft sensor bank 1. Nissan part # 23731-6J90B.

P1800 - Vias Control Solenoid Valve. You still have it on the car and the ECU still monitors it. It died, replace it.

 

Thanks! Ill get everything ordered. Do i need any certain brands? Nissan oem or can a save alittleon bosch and such

 

Get the camshaft sensor from Nissan. You can get the other parts from whomever you prefer. Bosch for the oxygen sensors are fine.

 

Do i want to the one with the metal end instead of the platic? I beieve it ends in c and the old one ends i b

 

Are you talking about the camshaft sensor? Also, what year is your car?

 

yes the cam sensor and its an 02

 

Originally the part number was 23731-6J905 and Nissan changed it to 23731-6J90B. I don't know if either one is better than the other. The part number changes for a lot of reasons. Maybe they have a different company supplying the part or maybe the old part didn't perform as good as it was supposed to.

In this case I think it was changed because of bad soldering on the little printed circuit board. There was a recall on the 2002 & 2003 because of this. The 2002 and the 2003 use the same part.

I forgot about this - there was a recall on the sensors. Before you buy the camshaft sensor, talk to the dealer and they can look up and see if the recall was done to your car. They need the VIN for lookup. If not, you will get both camshaft sensors and the crankshaft sensors replaced. The NHTSA Recall Number is 03V455000. There is also an air bag recall going on that covers your car and there two others back in 2002, one for the lower control arms and the other for the gas pedal stop.

You can also go on-line to http://www.nissanusa.com/recalls-vin#/ and enter the VIN of your car.

The site go back 15 years for ANY recalls on the car but it will tell you only about a recall that has not been done on the car. Any that have been done will not show up.

 

If it has been done and goes bad again do they cover it? I have a lower control arm thats shot due to a leaky ps hose. also

 

No, once the recall has been done, it is your problem. there is no extended warranty.

 

so part number bosch 15225 for both sensors?

 

The bank 1 and bank 2 oxygen sensors are the same actual sensor, but the wires to plug in the wire harness are different lengths. This would create 2 different part numbers. Sensor 15225 has wires that are 41 inches long. Sensor 15224 has wires that are 31 inches long.

On rockauto.com 15224 is $45.79; 15225 is $53.79.

I would order one 15224 and one 15225 and save $8.

 

your the man!

 

What's the part number for the metal ones?

 

Are you referring to the camshaft sensors?

When Nisan has superseded a part with a different one, you can only get the new one.

 

i ordered a genuine nissan cam sensor on ebay. It didnt come in a nissan package so I dont know that it is indeed oem. my nissan dealer wants 129 per sensor.

 

$129 is the suggested list price.

On-line:
$93.13 @ http://www.nissanpartsdeal.com/parts...731-6j90b.html
$97.63 @ http://www.nissanpartsdeal.com/parts...731-6j90b.html

Plus shipping charges. These are probably still more that e-bay.

 

Do I need to do both cam sensors and crank sensor all at once? Replacing the single one fixed my dying issue but its still hard starting.

 

Change em all

 

Before you go replacing parts just because someone on the internet said "change em all", let's try some diagnosing.

First, start by cleaning the engine ground connections. These are to the left of the oil filler cap. See drawing on page 340 in this link: http://boredmder.com/FSMs/Nissan/Maxima/2002/EC.pdf

Then, see what the ECT (Engine Coolant Temperature) sensor is reporting. This can be done with an OBD code reader, one that can display live data. (translation - not a cheap one, one that costs maybe $60) This will display the coolant temperature. Do this preferably when the engine is cold. If the engine is cold, the reading should be what ever the air temperature is. If the car has been driven, then the temperature should read 180 to 200º F, give or take a few. If the reading is off by a lot, the ECT sensor is bad and causing an incorrect fuel mixture.

Another way is to measure the resistance of the ECT. It can be done with the sensor in the car, just unplug the wire harness and measure on the sensor pins. At 70ºF, the reading should be between 2.1K and 2.9K ohms. At engine operating temperature, the reading should be between 235 to 260 ohms. See page 205 in the above link.

 

I went back up and had the codes read. It still shows bank 1 camshaft sensor

 

could you get me the part number for all 3 cam sensors? I want to order them all oem. im using my phone so that nissan site is tought to navigate.
