SOURCE: Can't find the fuel filter on 2004 toyota tacoma 4 cyl 4x4

With a 2.7 liter engine it is located under the intake manifold on the left side of the motor mounted to the engine block. It can be seen through the driver's side wheel well. 
Good luck and hope this helps.

SOURCE: have p0130 and p0133 codes 98 toyota tacoma

I would check the O2 sensor, and if it checks bad, replace it, and clear the trouble codes. If the light comes back on, you may need to check further. .

SOURCE: check engine light on 2003 toyota tacoma, O2 sensor?

An O2 sensor code is a tricky one. It could mean SEVERAL different things, and I know how bad it sucks to hear this, but your best bet is to take it in and have a diagnostic ran on it at either a dealer or a good mechanic shop with a computer they can hook up to it. I had an "O2" code come up a while back on another car I used to have, and literally spent weeks and hundreds of dollars trying to fix it, and never did. Finally out of desperation took it in, paid the $90, and they found the problem and fixed it in like 30 minutes. Something I would have never even thought of was causing it (can't remember off the top of my head). After that I stopped wating time and money on check engine lights. One comes on in my car, I take it to have it ran for free at and auto parts store just to make sure it's not a loose gas cap or something, just to get an idea of what I'm looking at, then go and make an appointment to have to hooked up to a diagnostic computer to track down the problem. Good luck, and hope this helps save you some time and money.

I got a po136 code when i change the exhaust box can it be the o2 sensor or the exhaust


This code indicates the downstream o2 sensor has failed. Make sure there are no exhaust leaks near the sensor causing false readings. If the connector/wiring is ok replace the sensor

2000 Toyota tacoma with code P0171.


You don't say if it is a 4 cyl or 6 cyl engine.
The code means the O2 sensor is telling the computer the engine fuel mixture is too lean and the computer can not make the injectors provide enough extra fuel to make the sensor go rich.
Reasons can be a faulty cooling thermostat, low fuel pressure, vac leaks, exhaust leaks, and other engine problems.

Where is the decelaration senser for the a.b.s. o4 tacoma 4x4


Diagnostic Test Code (DTC) C1244 is a "maufacturer-specific" code used by Toyota for this vehicle. Toyta defines this code simply as "DECELERATION SENSOR CIRCUIT."

Possible causes are:
> Faulty ABS deceleration sensor
> Open or short in deceleration sensor circuit
> Defective wiring harness or connectors

The deceleration sensor for your 2004 Toyota Tacoma is located under the passenger seat.

2005 toyota tacoma 2.7 code p0037 replace rear 02 and computer code keep coming back.


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.
