What controls the ground for the injectors on a 1992 toyota celica. I have sent out the computer and they sent it back saying it was ok. I have power to the injectors but no ground on # 1 & 3.


The ground goes into the computer to be internally grounded. Maybe bad wires in your harness somewhere.

#1 is a red wire, goes to ecu pin # 12 of the larger (26 pin) dark gray connector of ecu.

#3 ground wire is a yellow wire, enters ecu on pin 25 of same dark gray connector- Connector D.

Gave you that so you could check continuity of the wires. Hope you have an ohmmeter, a multi-meter. Good luck.

How do I check my main relay? 87 Honda accord lxi


check, ?
ok all relays
the relay is just a coil (mag) and a switch.
many relays have just 4 pins.
most main relays have 2 pins at 12v. one on the coil and one on the common contactor pin (input)
the ECU/PCM grounds the other coil pin, the mag field inside builds and the contactor closes. and the contactor ouput pin
goes to 12v and the ECU then powers up.

HOW?
how to check it, is easy, use a voltmeter, (never lies , like other ways)
any DMM , even that cheap one at walfart works great.
set the dial to 20vdc.
conn, black lead to car body, metal.
conn red lead to the 4 pins, 1 at at time and key on. (no start)
if the 2 pins do not have 12v(input pins) the fuse is blown or some dork cut the wires to install some , accessory.
now see the ECU ground the othe coil pin, 0volts,
the relay is now energized, (coil must not read infinity removed)
now check the output pin on said relay, if 0v , the relay is bad.
if 12v, on this pin, well , the relay is 100% OK.

to work on cars, you must learn electrics first, then how relays work. there are millions of web pages on this subject,

ok , i went to alldata.com (so can you)
and that car has 7 pin, MAIN relay.
black yell and blue black pins are 12v keyon.
yellow wire is fuel pump (early cars have 2 relays in one)
black is ground, if open , all is dead ! must be 0v
fuel pump enable line is green-black (ecu commanded)
0v when active, most cars take cranking to go active.
the blue-red wire from crank fuse. sends 12v to pump relay coil
for crank pump action.
and last but not least is the yell-black wire, this wire runs the ECU
and all injectors. this is 12v key on. if not check all coil pins on main.
i answered in the generic and exact.

old post. but lots of old handa's still ,

all this is on alldata.com or at mitchels.

Does anyone know what a transmission code 63 is for 1993 toyota t-100 with an a340e transmission? Thanks


On the a340e transmission that would be a shift solenoid circuit malfunction. You can purchase a "solenoid kit" that comes with two solenoids and mounting bracket, they can be easily replaced by dropping the transmission pan. They are attached with a single bolt (10mm)---Remove the bolt, unplug them from the wiring harness and pop them out of the ports they are seated in. Lightly coat the o-rings of the new solenoids with some ATF and insert them into their ports.
Good luck, i hope this helps.

I just need to know what the fuse numbered f16 in the power distibution center does. i need a full description


Fuse 16 (15 Amp) in the Power Distribution center (PDC)
powers circuit M1, (20 gauge, pink) which goes from the PDC
to splice S135.
.
From S135 it goes to pin 25 of the Transmission Control Module,
pin 1 of the Underhood Lamp/Mercury Switch and to pin 12 of
Connector 1 in the Junction Block.

At the junction block, it feeds
Connector 3 pin 3, Connector 4 pin S18, and Connector 7 pin 4.

From Junction Block Connector 7 pin 4 it goes through Connector
C314 and powers the Cargo Lamp.

From Junction Block Connector 4 pin S18 it goes through splice S214 and connector
C208 to power the left courtesy lamp. From S214 it also goes to
Connector C1 pin 9 in the instrument cluster, through connector
C207 to the right courtesy lamp, and to connector C2 pin 7 at
the radio.

From Junction Block connector C3 pin 3 it goes to splice S361, where it then feeds
the right visor/vanity lamp and to splice S347 where it splits off and feeds
the overhead module, the left visor/vanity lamp, compass (If equipped) and
the dome lamp.

1998 rav 4 ecu pinout location


sorry never done one so i havent a clue,in the good old days the tach connected to the coil wire but now with all this fancy electrics ,Well what happens is they call it vehicle security so they dont have to release the diagrams and this is done to stop people like myself from by passing the immobilisers when we service a vehicle.Because no doubt as you are aware on new cars that if you drop the oil the immobiliser cuts in.Change the battery and the same thing happens.So what happens to keep the dealers in work ,yes you have guessed it no wiring diagrams ,multilayered circuit boards and wires all the same colour to stop people like me from soldering the two outside legs together of a big switching transistor together to make the vehicle general mechanic friendly.Also encrypted software is used to stop the fault codes from being read ,they throw up the wrong code ?? try asking dealer to install then post where he connected too .,best of british with it
