SW20_Taylor

Thank you for the advice Vaughan. It does stay 0 kpa while engine running. I'm trying tp use the sensor for oil pressure so I can add it as a perimeter in my RPM and MAP limit tables.

Thank you Adam, I adjusted the error values and now I have no codes. Is it alright to have 0V for error low and 5V for error high or should I adjust it to .1V and 4.9V respectively? The Temp sensor is now working, it just needs a pull up resistor, but i'm still getting O KPA reading for the pressure. If I change the pressure value for .5V in the calibration 8 table from 0 KPA to any number the reading will change to that set number. This is telling me its seeing .5V but its not varying. I've tried Linear calibration table 6 (since its a linear sensor) and a non linear calibration table 8 that matches the cal sheet provide by Rife but still no luck. Any suggestions?

I have a g4+ plug in, MR2 V3, with a Rife pressure and temp block. Its a dual sensor block with a 150psi pressure sensor and a remote temp thermistor that connects to the sensor black via a M5 cable. They share 5V ref and ground. I've confirmed I am getting 5V from the expansion harness and at the sensor. Rife said I should have .5V at the pressure output which I did confirm with my multi meter. Calibration set to Cal 6 since its a linear sensor and per their instructions set 0.5V = 0 PSI; 4.5V = 150 PSI on the calibration. Error low set to .5V I get code 23: Error AN V5 at GND. If I put error low to 0.0V I have no fault codes. I get no reading for oil pressure, stays at 0 KPA, regardless of Error values. Am I correct to have Error Low set to 0.0V and rule that out? I'm just trying to get this sensors working so I can implement more protection strategies. Not sure where to go from here since I have 5V ref, sensor ground, and correct voltage from the sensor. Maybe check the pins on the connection from the expansion loom to the ECU? Defective Sensors? Please advise.

I have the same ECU as stevel48, how would you go about wiring up antemp4? I'm running my wideband on anvolt7 with the expansion loom currently. I plan to run oil pressure to anvolt6, fuel pressure to anvolt5, and oil temp to antemp3. I still have fuel temp to wire up and I think I would rather make antemp4 work depending on what it all involves. Would I be better off getting a second expansion loom and running a pull up resistor then what's mentioned above? I guess I could also use the anvolt4 pin from the ecu plug and run a pull up resistor as well, but i'm trying not to hack up the OEM harness.
