Ok I uploaded the Wiring Diagrams for the Engine Performance for the L Engine (I can't find anything on the I don't think they used.
How To Discover If You Have Wideband Or Narrowband O2 Sensors NOTE: MOST poor results can be traced to an incorrect installation of the EFIE using the wrong sensor wire- The sensor can have 2, 3 or 4 wires (some can have 5 or 6- these are rare), and present in a few Chrysler/Dodge/Plymouth & Jeep models. The two white wires are for the sensor heater and do not matter.
Case Image 98 Sport Coupe The downstream is used mainly to check the efficiency of the cat. converter. A cheap source for the 33 year Chrysler Tech.
Top. But there are other possible causes for a heater DTC. Before screwing in Usually the heater wires on the sensor's harness are both either black or white.

If your car has a 4-cyl then there is only one downstream O2 sensor.
This is where you need to start the diagnosis for code P While it would be nice to assume that the sensor is faulty, the sensor wiring between sensor and PCM could be the problem as well. May 24, · I was going to use a 4 wire sensor but to run the wiring was too much trouble so I used a universal 3 wire o2 as it was easier to install.
Btw - 87 did not have 4 wire sensors, starting in 88 did Toyota use 4 wire sensors. What I do remember is the following: The Blue is signal + (the original o2 wire). Let’s take a Dodge Ram L, for example.
By looking at the wiring diagrams (see Figures 5 and 6 for wiring diagrams provided by Mitchell 1 ProDemand), we can figure out which wires belong to the oxygen sensor heater circuit by simply matching wire colors. There are 4 wires on the oxygen sensor of my Dodge Ram truck.
