2004 corolla looking for the right wire for tach signal at pcm they said black wire position 5connector e6 theres 2 black wire side by side i dont see any number on connector need some wiring diagram at pcm

PASSIVE ANTI-THEFT YES TRANSPONDER SEE NOTES 12 VOLTS Yellow Ignition harness IGNITION RED / green Ignition harness IGNITION 2 Blue/green This wire is only required on the V-10 Gas engine. ACCESSORY RED / black Ignition harness ACCESSORY 2 Gray / YELLOW Ignition harness STARTER Dk.green Ignition harness KEY SENSE BLACK/ pink In airbag plug on right side of st. column TACH SIGNAL Use an injector DIESEL TACH SIGNAL GREEN / WHITE SEE NOTES Look below the relay box under the dash for a large loomed harness. There are some wires taped to the harness terminated with heat shrink tubing. You will find the GREEN / WHITE among these wires. LOCK WHITE/ red In harness above gas pedal On 4 door models, these wire are negative trigger. Vehicles with no keyless entry, colors are Pink / YELLOW for lock and Pink/green for unlock in 5-wire reverse polarity. They will be found in either kickpanel. UNLOCK BLACK/ white In harness above gas pedal On 4 door models, these wire are negative trigger. Vehicles with no keyless entry, colors are Pink / YELLOW for lock and Pink/green for unlock in 5-wire reverse polarity. They will be found in either kickpanel. DRIVER LOCK MOTOR Pink/black In harness above gas pedal DRIVER UNLOCK MOTOR RED / orange In harness above gas pedal PASSENGER UNLOCK MOTOR Pink/orange In harness above gas pedal GLO-PLUG SIGNAL DATA ONLY USE DELAY TIMER DOORPIN BLACK/ blue Above parking brake in DKP The vehicle's computer sends out diagnostic pulses on this wire every 15-20 minutes. This may cause an after-market alarm to false. It is suggested that you add a relay to this wire when connecting to an alarm system. See the appropriate diagram for exact wiring instructions. FACTORY ARM Yellow/black Above parking brake in DKP This is the driver's doorpin wire. Pulse this wire at the same time as lock to arm the factory alarm.

The connector for cam sensor shows three wires, that should be ref voltage-pink wire, black with white tracer- ground, signal-black wire. The signal wire carries signal to pcm. To check signal, is you have a digital multimeter that has a tach--duty cycle or dwell setting, they should react to a pulse on the signal wire. The ref voltage is 12 volts, probably goes hot with key on. The black wire with white-ground use an led testlight to check ground, should be computer safe.

There are several circuit that use the same 12 volt reference.

It is above and behind the Alternator on the top. It looks like a "D" battery standing-up with a female pigtail hook-up on the top of it.

If the tach was an option for your corolla, it is very likely that the wiring harness in your car would have the connector for the tach. They would use the same wiring harness to cut costs, and whatever is not used would be left open on a car without a tach. You will have to find a wiring diagram to check for the tach connector-it would be up under the dash leading to the cluster. In earlier days, tachs were connected to the coil's negative side of the primary circuit.

Look it up here http://www.bbbind.com/free_tsb.html free wiring diagrams , Enter vehicle info. year , make , model and engine size .
Under system click on engine , under subsystem click fuel controls . Click the search button , then the first blue link . The 7 th diagram down is for O2 sensors . The ppl wire to pin 21 is signal return , the tan to pin 7 is low ref, ( ground ) Tan / white pin 26 low ref.(ground ) PPL / white pin 22 signal return .

the trouble codes are as follows code 12 problem with battery connection. direct battery input tp pcm disconnected within the last 50 ignition key-on cycles. code 15 a problem with the vehicle distance/speed signal. no distance/speed sensor signal detected during road load conditions. code 55 completion of fault code display on check engine light. this is an end of message code. the speed sensor is located on the transmission/transfer case extension housing. check plug connection to speed sensor for power using an volt meter. connect the positive side of volt meter to the orange wire terminal and the negative side of volt meter to the black/light blue terminal. the voltage should be approximately 8.0 volts and to check the voltage from the pcm connect the positive end of volt meter to the white/orange wire terminal and the negative side ti the black/light blue wire terminal. signal voltage should be 5.0 volts. if there is no signal voltage signal, have the pcm checked out. if you have both signals from the terminals then remove the vehicle speed sensor and check the speedometer pinion for worn or missing teeth.

It is usually to the positive side of the coil - also depends on what type of distributor cap you have, if there is a 3-4 wire plug that goes to the cap, one of them should be marked TACH

Do the following:1)key in the ON position:remove the 7.5 gauge fuse.Tach needle should read "0:". 2)put it back,go on the engine and unplug the green plug on the igniter -the big one,with 5 or 6 wires on it.The needle on tach reading should be zero.If not you have a short circuit on the black wire between that plug and the plug on the conbination meter.3) If the reading is zero with the plug disconnected,the black wire for the tach is short-circuited inside the igniter. I have one available.email [email protected]

That wire is for a tachometer.If not using a tach do not connect it.

you can also solder the wire to the tach wire, this way it won't come off and cause a malfunction
