Changed motor from 1az to 2az . knock sensor wiring is different 1 wire 1az 2wires 2az .how do i hook up properly.

the ECU is last never #1. ever. in fact it is good. and why replace the most expensive electric part on the car .
fuse are first, and sensors unplugged.
wow. that was brave.
gee did 1 spark fails or all 4? not doing all 4 is so wrong.
if all 4 die, CKP /CMP tests are next.
no turbo right? 2.0L DOHC chain drive, miles on it are?
wow fuses all good is first not $300 parts.
is this a USA car, not told why skip #1 important fact .????
in the USA we have OBD2 cars 1996 up. (our invention)
but not VOXY sold to ASIA, are you in ASIA market????????
and all scan tools here work at that DLC port.
and we scan it.
are you sure 1998 is correct wiki show 2001 up 2019
there are vast 1AZ engine even 1AZ-FE (fuel injected) up and VVT
or 1AZ-FSE?????
what is there ive not one clue. and lots of voxy submodels exist.
same car as the Toyota Noah

I see no 1998 on earth sold called that. why?
no country told and is not sold here USA.
i will make list of no spark, modern 1AZ-fe
random order.

1. cam does not turn or is timed wrong. chain snapped
2. cmp dead cam sensor dead or # 1 cause.
3. CKP crank sensor dead,
4. coil packs 2 of them or 4 COP's all dead.
5. bad wiring related;.
6. ECU bad, rare.

SOME 1AZ USE 4 COPS AND OTHERS USE 2COIL PACKS THAT RUN 2 SPARK PLUGS CALLED WASTED SPARK]
AND IF SAY SPARK#1 IS DEAD, IF SPARK 1 OR 4 SPARK PLUG OR HV WIRE IS OPEN BOTH DIED. DEAD. FOOLING YOU.
COP'S MEANS COIL OVER PLUG AND IS 4 SPARK COILS
AND ALL4 MUST BE TESTED OR GO WILDLY ASTRAY YOU WILL
THE ONLY 2.0 l 1AZ IN USE 1980 IS RAV 4.
SO YOU ARE NOT THERE. TIME TO BRAVE UP AND TELL

In stead of changing what is not wrong, save money and time by having the fault codes read and fixing the fault
check engine lights refer to both an engine problem and a transmission problem so what you may have could be in the transmission.

on the side of the engine,
why do you need to know that.?
they never fail unless hit with a hammer.
the answer is in the FSM (no engine options stated so impossible to answer prefectly)
its at alldata.com, but you need engine size.
here is the engine list just for all (in year span) RAV4

2.0 L 1AZ-FE I4 (petrol)
2.0 L 1AZ-FSE I4 (petrol)
2.0 L 3ZR-FAE I4 (petrol)
2.2 L 2AD-FTV I4 (diesel)
2.2 L 2AD-FHV I4 (diesel)
2.4 L 2AZ-FE I4 (petrol)
2.5 L 2AR-FE I4 (petrol)
3.5 L 2GR-FE V6 (petrol)
world wide, and you never said what country either.

What you propose will not work with your pcm. If you have 2 wires to the knock sensor, one is probably a reference wire and the other a signal. The computer will throw a code and will not understand the return signal.

Looks like the wire from the sensor to the module is dark blue.
You can find the engine diagram on autozone's website under repair help.

knock sensor problems arise from ---wiring --poor connections --knock sensor----insecure KS--KS incorrectly tightened ---wiring short to positive --wiring short to ground ---ECM
as you can see , there are more causes than the KS itself so care should be taken in the installation, tightening , wires and make sure that the area is water proof

A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block.

This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0330.

Symptoms: You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.

Causes: A code P0325 most likely means one or more of the following has happened:
* The knock sensor is faulty and needs to be replaced
* There is a wiring short/fault in the knock sensor circuit

Possible Solutions
* Check the resistance of the knock sensor (compare it to factory specs)
* Check for broken/frayed wires leading to the sensor
* Replace the knock sensor


Test it and tell us news.

It sounds like you got a 2001 motor. The 1999 and 2000 use the one wire knock sensor and screws into the block, the 2001 has the two wires and bolts to the block. I would think that you could use the one wire sensor screwed into the block of the new motor, but I would verify for sure that everything else with the new motor is compatible with the 1999. I would suspect that there may be some other issues of compatibility. I would check with a GMC dealer, but I think you may have the wrong motor.

You cant make it work, you need to get the correct sensor.

po325 knock sensor 1 malfunction po340 camshaft position sensor malfunction po605 internal control modular (rom) read only memory error check the wiring to the computer for proper connection and damage the computer (pcm) may be damaged or its program erased this happens sometimes when the connector is unplugged and the battery is hooked up the other two can be related (pcm) failure or could be a wiring problem po325 check knock sensor wiring and sensor and same for po340 crank sensor wiring and sensor good luck
