Codes Codes and Codes...Am I reading these right? (video included)
Hey guys, pulled the codes on my 90 GTU, I'm pretty sure I am interpreting these right, but I want to make sure, so I figured I'd ask for some clarification.
I'm seeing the following, if I'm misinterpreting these, let me know Codes: 13 Pressure Sensor 17 Feedback system 27 Oil Metering Pump 37 Oil Metering Pump. 27 and 37 (if im interpreting these right) obviously means I need a new OMP, and most likely ECU. However, I am not sure about 13 and 17. any advice would be much appreciated. |
13-Swap in a new pressure sensor or check the harness at the ECU for continuity
17-O2 sensor-New sensor or wiring broken in harness, check continuity |

17-O2 sensor-New sensor or wiring broken in harness, check continuity as for the 13, here is my issue, I replaced the pressure sensor with a compatible working one I got from Kevin at RotaryResurrection. After driving for awhile and clearing the codes, I still have the code 13. So i'm guessing either I bought a bad sensor (which I doubt, but still possible) or there is something wrong between the wiring and the ecu. Looking at the manual it lists these as the trouble shooting options: https://cimg2.ibsrv.net/gimg/www.rx7...895aaef1a9.png My question is, about checking the continuity between the sensor and ecu, I'm assuming I use the leads in the multimeter on the plug side of the harness, and then touch the other lead to the corresponding plug on the ECU. Seems like I'd need some rather long lead cables. |
Jumper wire instead. Pull plug at sensor, put wire in pins and read. Then do the reverse at the other end of the wire to double check.

Codes...I got codes... in different area codes, area codes.

There are only 3 wires to test, so with the plug connected to the sensor and w/key to on, test the voltage on the 3 wires and compare to spec. This is an easy and brief test.

A sensor doesn't have to have an error code to test the input/output voltage of the wires in question. If in the future if it did throw a code you would at least have a set of numbers to compare it to.
