Hopefully you just blew a fuse or two and not cooked the engine computer.

SOURCE: how to change spark plugs in 02 toyota tacoma v6

You need a special tool when they are stuck on, it's like a long pair of neddle noise plyers with sides that grabs the wire by the boot evenly, but twist them loose from the plug as you pull the rubber actuaully melts itself to the plug sometimes

SOURCE: Hooked up battery cables backwards now my 200

You have shorted and fried fuses, you are going to have to go to the main fuse box and the fuse box under the dash and start replacing fuses,

SOURCE: 02 saturn car starts then shuts off within 5 sec

Check security light, if it is flashing , it is set. try this, turn ignition on, don't try to start, let set for ten minutes on. turn off don't take the key out. do this three times ten minutes each, after the third time turn it off, then try to start. This resets the security. If this does not work, then it needs reprogrammed to the new computer you installed. dealer only, about $100.00

SOURCE: 2005 toyota tacoma 2.7 code p0037 replace rear 02

P0037 - O2 Oxygen Sensor Circuit High Voltage (Bank1, Sensor2)

The Heated Oxygen Sensor (2) located rear of catalytic converter produces an output signal relative to oxygen storage capacity of catalytic converter. Ho2S 2 signal is less active than signal produced by front oxygen sensor. This code sets when HO2 Sensor voltage is greater than 999 mV for more than 2 minutes (time depends on model. Could be as high as 4 minutes)

Symptoms: There may be no noticeable symptoms except for MIL illumination. Possible high fuel pressure can over rich the system.

Causes: A code P0138 may mean that one or more of the following has happened:
* Faulty O2 sensor
* Short to battery voltage in O2 sensor signal circuit
* High fuel pressure (not as likely)


Here are some potential solutions:
* Replace O2 sensor
* Repair short to battery voltage in o2 sensor signal circuit

If you replaced the O2 sensor, then its possible that you have some electrical problem there; reset the codes first, and if this come on again, check in this link TSB P0037 electrical diagnostic procedure.

Keep us updated.

No acceleration gas pedal


Sorry to say, sounds as if you had cables hooked up backwards, or possibly just had very poor connection between battery and battery cable terminal. If you may have had jumper cables connected backwards, you may have fried some electrical component. Get someone to read the codes which are making the check engine light come on, and perhaps this will give a clue as to what component is blown. Could have damaged anything from a small sensor to the main computer, in which case I would check with salvage yard for a used unit. The main computer is quite pricey.

Recently hooked up jumper cables backwards on my 1999 Toyota Tacoma. Now truck is completely dead. Is this a fuse problem?


Begin by replacing the battery. If this doesn't take care of the problem, also replace the alternator and check each of the fuses. J.

Try turning the key in the driver side dorr after you hook the battery back up.I had a Nissan Maxima with the same problem and that did the trick.Its worth a try.

Horn/lights on 2002 Toyota Tacoma


Rewire your horn from the steering wheel to the horn. Its not difficult, I can't tell you how to take the steering wheel apart but you can get a Haynes Repair Manual. It'll have all you need and more. You can use speaker wire, split it in two. Run one cable from the positive in the battery to the horn switch in the steering wheel. Another from the switch to the horn. You have a short somewhere, to me is easier just to run new wires than to find the short-circuit. Make sure when you run the cables through the firewall you run through a grommet so it does not get damaged by metal. Before anything check your headlight wires that they are not touching the horn.

Reversed Batter cables


Check both fuse boxes again. You have a blown fuse somewhere and it most likely is one on the main fuses in the underhood fusebox.
