need help with my 93 toyota camry?

Brandon

i have a 1993 toyota camry. a while back the hydrolic fan was leaking so we replaced it with an electric fan and we taped into the ignition wire for the plugs and knock sensor then we lost power and had an over heating problem found out that the water pump was leaking and put some block sealer in it and it no longer leaks but still no power so we had the codes pulled both knock sensor codes came up so we moved the fans power line to a better spot but still no power so can i reset knock sensors and how if not where are they and do they have to be replaced

can't reset antiknock sensors.















one would reset the ecu. pull EFI main fuse for thirty secs. key off.















adding components to the antiknock sensor circuit will skew the info sent to the ecu thereby skewing fuel mixtures. adding anything to the ignition circuit can take out a coil and likely effect timing.































hope you used a stop leak in the coolant and not a "block" sealer. stop leak is bad enough, but block sealers should be outright banned.































since you have done some "back yard" wiring, i don't see how we can be of help to you.































suggestion,















i would first start over. go back to oem config/wiring on everything.















then pull codes. don't need a scanner tool. have it blink at you,

FYI,















the primary fan is not in the ecu loop. it uses the radiator temp sensor on the rad itself for function. power is sourced from the fuse/relay box in the bay. the second fan (app) is controlled by the a/c circuit.















correctly wired, if it were just the fan not coming on, i'd look at the temp sensor on the rad, fuse/relay, thermostat, or a faulty connection/wiring issue. not the ecu.
