Can anyone help me I have a 88 toyota pick-up and it is throwing a code 52.
I recently swaped a motor from a 86 4 runner into it so I thought I would swap the one of of that or so I though. The sensor that I swaped aparently is
for the oil pressure gauge it was on the passengerside of the block under the oil filter. So with that being said were is the knock sensor and what does it look like?

Also when I swaped the engine I also swaped the cluster because it had a tach and actual gauges instead of idiot light but the temp does not read
acurate any ideas?

 

The knock sensor is next to the fuel filter, the fuel filter is close to the oil filter

 

is it in the block or the intake?

 

block on the 22re.

 

In the block, yellow connector at about the 9:30 position next to the oil filter:
