Important Tips and also Suggestions

TIP 1: The tests the you are around to do, v the LED light, call for that you revolve the engine by hand. To it is in a bit much more specific, friend cannot usage the starter engine to crank the engine to carry out TEST 3 and TEST 4.

TIP 2: The fuel mechanism must it is in disabled before you execute TEST 3 and also TEST 4. You can easily do this by remove the fuel pump fuse.

The fuel pump fuse location:

1997-2000 3.3L Infiniti QX-4: fuse #17 that the dash fuse box.1999-2002 3.3L Mercury Villager: fuse #43 that the engine compartment fuse box.1999-2004 3.3L Nissan Frontier: fuse #1 of the dash fuse box.1999-2002 3.3L Nissan Quest: fuse #43 of the engine compartment fuse box.1996-2000 3.3L Nissan Pathfinder: fuse #17 of the dash fuse box.2000-2004 3.3L Nissan Xterra: fuse #1 the the dash fuse box.

TIP 3: prior to you test the camshaft place sensor, friend must an initial test the ignition coil. If the ignition coil sparks climate you have the right to conclude the the camshaft position sensor is great and work correctly.

The ignition coil test is not difficult to and you can find it here: power Transistor Test and Ignition Coil check 3.3L Nissan (1996-2004).

TIP 4: If it transforms out that the camshaft position sensor is bad, you"re gonna" need to buy the totality distributor, since Nissan in all its wisdom, does not license any kind of of the materials to be marketed separately.

How does The Camshaft position Sensor Work?

Here"s a an extremely brief summary of how the camshaft place (CMP) sensor works:

The camshaft place sensor is located inside the distributor and also is part of the strength transistor assembly.The cam sensor assembly is really a crankshaft place sensor, because the fuel injection computer system uses that to regulate the production of spark (thru") the strength transistor and also ignition coil.Now, as soon as you revolve the an essential and crank the engine (to start it), the cam sensor/power transistor get power thru" the cable labeled v the number 5.As the engine turns, the video camer sensor assembly beginning to produce two details position signals that it sends straight to the computer. One signal is referred to as the 1° POS signal and the other is dubbed the 120° REF signal.When the computer gets these two video camer signals, the does its little song and dance and shoots an activation signal to the power transistor.When the strength transistor gets its activation signal native the fuel injection computer, it currently starts to switch the ignition coil"s strength ON and also OFF. This ON/OFF activity is what makes the ignition coil spark and also is referred to as the switching signal.

When the camshaft position sensor fails on her 3.3L Nissan Frontier, Pathfinder, or Xterra; the engine is no going come start as result of a lack of spark.

You"re additionally going to watch a P0340 trouble code registered in the fuel injection computer. This code will certainly light increase the examine engine irradiate on your Nissan tool cluster.

TEST 1: Making sure The Camshaft position Sensor Is getting Power

*

In this very first test we"re gonna" make certain that the camshaft position sensor is obtaining 10 come 12 Volts.

The wire the feeds this 12 Volts to the camshaft position sensor is the one labeled v the number 5.

On the Frontier and Xterra, this cable is the black with pink stripe (BLK/PNK) cable of the distributor"s 6-wire electrical connector.

On the Quest, QX-4, Pathfinder, and also Villager; this wire is the black through white stripe (BLK/WHT) cable of the distributor"s 6-wire electrical connector.

If this 12 Volts are current then the following step is to make sure the camshaft position sensor is getting Ground.

These room the test steps:


Your multimeter should register 10 come 12 Volts DC.

Let"s study your test result:

CASE 1: your multimeter registered 10 come 12 Volts. This is the correct test result.

This an outcome confirms that the camshaft position sensor is acquiring power. The following step is to make certain that it"s getting Ground. Go to: test 2: Making sure The electronic came Sensor Is acquiring Ground.

CASE 2: your multimeter DID not register 10 come 12 Volts. There is no this voltage the camshaft position sensor will not function.

Your next step uncover out why this voltage is absent and repair the problem. The complying with ignition system wiring diagrams will aid you map down the problem:
