Service Engine Soon Light

There is a way to get codes from the vehicle without tools!!
This is the procedure:

1. Confirm that accelerator pedal is fully released, turn ignition to the on position and wait 3 seconds.
2. Repeat folowing procedure quickly 5 times within 5 seconds.
a. Fully depress accelerator pedal.
b. Fully depress accelerator pedal.
3. wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the mil light starts blinking.
4. fully release accelerator pedal.
note: It is better to count the time accurately with a clock.
The ECM returns to normal conditions when ignition switch is turned off.
The number of blinks indicates the DTC code!!

Quite a ritual you have to perform there, for sure!

Actually it's not, I read that right out of the service manual!!

I wouldn't do that to you guys!!

section #, page #, and page # for codes!

I've only seen one titan with a check engine light on .My dealer told me that he had a hole in his cat, I dont know if thats your problem. but you may want to have it check out anyway

That is so intuitively obvious as to require no explanation.

Now you know what the Tech's have to try and decipher in the service manuals!!

I don't know about you, but I would have taken my 'cat' to the vet if it had a hole in it.

I changed my oil this weekend and a day later the "Service Engine Soon" Light came on. I used Mobil 1 synthetic and a fram filter. Any suggestions before I take it into the shop?

Wow, talk about reviving an old thread.

I'd get to a shop ASAP to figure out why it's throwing the light... i've never heard of this happening during an oil change.

Hello Nissan Titan lovers,
I have a problem and needs all your help. I have the LE model and my reverse light and sensor are not working when i back out. I have this two code P1168 and P1286. Do anyone knows what i need to do to fix what this problem is and thanks you all in advance.

P1168 Closed Loop Control (Bank 2)

DTC: P1286
Search Bulletins/Recalls for P1286

Trouble diagnosis name: Air fuel ratio (A/F) sensor 1 (Bank 2) circuit high voltage

Component Description

The A/F sensor is a planar dual-cell limit current sensor. The sensor element of the A/F sensor is the combination of a Nernst concentration cell (sensor cell) with an oxygen-pump cell, which transports ions. It has a heater in the element.

The sensor is capable of precise measurement λ= 1, but also in the lean and rich range. Together with its control electronics, the sensor outputs a clear, continuous signal throughout a wide λ range (0.7 < λ < air).

The exhaust gas components diffuse through the diffusion gap at the electrode of the oxygen pump and Nernst concentration cell, where they are brought to thermodynamic balance.

An electronic circuit controls the pump current through the oxygen-pump cell so that the composition of the exhaust gas in the diffusion gap remains constant at λ = 1. Therefore, the A/F sensor is able to indicate air/fuel ratio by this pumping of current. In addition, a heater is integrated in the sensor to ensure the required operating temperature of 700 - 800°C (1,292 - 1,472°F).

DTC detecting condition:

The A/F signal computed by ECM from the A/F sensor 1 (Bank 2) signal is constantly approx. 1.5V.
Possible cause:

Harness or connectors (The A/F sensor 1 circuit is open or shorted.)
Air fuel ratio (A/F) sensor 1
