Razamataz I tested the sensor

[quote:e0a3434e65="96realwe"]As Razamataz suggested I read the resistantance of the water temp. sensor, cold it reads 2.5 as it warms up it drops to 0.2 completely warm, I am trying to diagnose error code 22 on a 1987 toyota camry 108,000 miles, auto, 4cyl, if Raz is still there or anyone with an idea please help[/quote:e0a3434e65]

The sensor is good-now remove the EFI fuse for 10sec or better-place back in-start vehicle is it still there. Comeback and I'll give you more headaches. I'm here now

Razmataz pulled fuse light went out than back on what next?

Okay, now check the reference wire on the connector do you have 5volts.

raz connected multimeter to both terminals both leads (red) and (blk) no voltage across connector

Did you turn key On-if still no voltage-troubleshoot the wire all the way to the PCM

yes key on

Raz where is the PCM looked under the hood, also checked for contnuwity with plugs and 6 in down on wire both are good to the harness
