Double the resistor size or even triple it, and you will find the device is much less sensitive. What do you think about resistor mod. No, the post cat sensor will remain a nearly flat line when the engine is a steady speed, if the catalyst is good. These are the best set of power harnesses on the market. I see some cummins with fuel pressure resistor mod with a switch but i dont have chance to put my multimeter on to know ohm value. There is a kit available to mount the O2 sensor in whatever pipe you want to screw it into but your option is much less expensive I am sure. It should read 0 psi without the wire.

"ItemImage467" : "/wcsstore/CATCAS/CM20190718-35df4-2406d", So simply fitting a resistor to indicate more boost pressure and less fuel pressure will not work, it will log a fault for the non 0 boost pressure sensor, and any other pressure sensors with resistors in the circuit. I have read that on some years this was a known issue and a software update can resolve this. You can compare only upto 4 items.Uncheck something else to add this.

You can't bypass the oxygen sensor with a resistor. shopperActionsJS.setInventoryAvlQty(137); VOID WHERE PROHIBITED OR RESTRICTED BY LAW OR REGULATION. Buy 2. The old way to defeat that problem was adding a resistor in line with the boost pressure sensor feeding the ECM, the MP-8 does that for you and a few other nice things. You can make the device less sensitive by using a larger resistor. one goes to the fuel temp sensor and the other to the boost sensor. theres two diagrams on the page, the first one shows the 1µF cap connecting the blue and white wires (both blue and white wires still connect to the o2 sensor also) and a 1MÙ resistor running through the blue wire to the o2 sensor. HI , Its a resistor that replaces the oxygen sensor (i think), so the cat converter is bypassed. The computer only needs a reading of 50 ohms from the o2 sensor to keep the 'check engine ' light off.So a resistor can replace the o2 sensor to bypass the cat converter.it has worked for me for 4 years... saves me gas too!!!thanks. HI , Its a resistor that replaces the oxygen sensor (i think), so the cat converter is bypassed.

It is more than just a wiring harness, there is a resistor in the wire to cause the sensor to send an altered signal to the computer, thereby fooling it into sending more or less fuel to the injectors. However the one code covers no less than five different faults, as follows:-0102-01 - low boost pressure 0102-02 - boost pressure signal erratic 0102-03 - boost pressure sensor voltage high 0102-04 - boost pressure sensor voltage low Description: Pressure sensors use capacitance or strain gage-based technology that generates an output signal (Analog or PWM) that is proportional to the applied pressure. ]. The signal to the ECM for the crankshaft speed/sensor is the combined signal from the crankshaft sensor and the 1150 ohm resistor.

This is for an adjustable boost harness and fixed fuel temp harness. note l: 12 volt battery systems must use the dc/dc converter ... use this sensor for underground mining applications only. Spicing into the pre cat o2 sensor would be a bad idea because you are going to change the load changing the voltage the ecu sees causing incorrect fuel trims. The reason non foulers work is because the head of the o2 sensor is pulled out of the direct exhaust stream but it still is picking up whiffs causing the ecu to see activity.
