WHERE IS THE KNOCK SENSOR LOCATED ON A ?

2003 Toyota Camry • 140,000 miles

I just ran a OBDII scan on my 2003 Toyota Camry: LE; 4 Cyl 2.4L, automatic transmission in which it gave me a P0325 code. I know this has to do with the knock sensor. My question is, where is it located on this vehicle & what do I have to do to get to it in order to replace it?

It just screws into the side of the block.

NOTE: Knock sensor may also be referred to as knock sensor No. 1.

Removal & Installation (Camry)

1. Knock sensor is located on side of cylinder block,  just below intake manifold. See Fig. 10.
2. Service information is not available from manufacturer. It may be necessary to remove engine with transaxle to gain access for removal of intake manifold. For engine removal,  see appropriate article in ENGINES.
3. It may be necessary to remove intake manifold for access to knock sensor. Use Oil Pressure Switch Socket (SST 09816 30010),  or equivalent,  when servicing knock sensor.
4. Tighten knock sensor and intake manifold bolts/nuts (if removed) to specification. See TORQUE SPECIFICATIONS.

So, I won't have to take off the intake manifold to get to it then, right?

Sorry, hmac300! I didn't see your response at first. It looks as though I'll have to take off the intake manifold in order to get to the sensor, unless I can find an extension wrench. Why do they have to make everything so difficult & frustrating to get to?

Because they make cars to assemble not repair. Engineers don't think that way because they have never repaired a car.

Well said! Thanks for your help! I think I have a better understanding of where it's located & what it's going to take to get to it, now. Also, I was told that I can tap the engine block to make sure it's not just a lose wire or corrision built up, first.

If you have the correct tool then you don't need to remove the manifold.

Yes you can do that with tapping the block
