91 lexus 2vzfe- code 52-HELP!!!

[jjewell]

I've gone over the whole circuit for/including the sensor-reset ecu-chem treated fuel system-keep getting the knock sensor code! Been searching threads for days- no real solutions. Saw one thread suggesting a resistor to simulate sensor signal to ecu. Anyone done this? What value of resistor?

I gotta get this car smogged- running out of time! Please, can anyone give me some help? I've also gone over the fsm- still no good. My fingers be very sore for the searches. OR..................
Would I be better off getting another knock sensor, mount it where it's easier to get to & wire it in? Are they position sensitive?

The car runs great regardless of the code, but it (cel) sure is wearing me down!

try wiring a resistor in in place of the kock sensor when you go for the test.
then when you have the money replace the sensor properly.
it's there for your protection.
BTW if you move the sensor/bypass it run ONLY premium just in case

Thanks for the reply! Do you know what value (ohms) the resistor should be?

[internetautomar]

no
I know that we used 470k on the max
but I'd find someone who has a new one and measure it's resistance.
use that resistance to "fool" yourself.

just make sure to replace it ASAP though. otherwise the potential for engine damage is elevated.

cool. was the max the same engine as mine?

[internetautomar]

no, but it also used a knock sensor mountedin the middle of the cylinder banks
