The probes are available on the site at a price of 87 euros (or from autoparts123) The proper tool to remove the probe I order two of these in case both the o2 sensor were dead or to have a spare one. The universal sensor is supplied a universal plug which can be connected to the genuine connector. According to their catalog, the universal model number 0 258 005 726 can replace Nissan 22690 24U0 24U01 (among others). On page 504 we find the references of the genuine sensor … and its universal model replacement: 0 258 005 726īosch offers universal oxygen sensors that replace many existing and legacy models.
After a long and painful search and some interesting leads (NTK sensors, the site Nissan parts and alternatives), I ended up finding this Bosch document (pdf 10MB, 519 pages). It seems overpriced since it is Bosch made and the price of common o2 sensors usually oscillates between 80 and 100 euros. Genuine sensors cost lots of money : over 245 euros for 2 probes (available at Kudosmotorsports for example). The oxygen sensors installed on the car are from Bosch (it’s writen on it) and the Nissan part numbers are 22690 24U0 24U01. When the sensors are operating normally the diagram is as follows: On the image below showing the signal of 2 sensors of the car it is clear that one them does not oscillate but is completely dead. At idle the standard electrical signal is a sinuzoïde oscillating between 0 and 1 Volt. One can observe the behavior of oxygen sensors … and this is how I saw that one of the two sensors were stuffed.
The software can monitor most of the sensors / probes of the car and you can save the data to analyse it off-line.
The CO must be lower than 0.3% at idle to register the car in France (all cars built after 99 must meet this standard or they cannot pass the French MoT) I decided to invest in the Nissan DataScan software with USB cable available from Blazt.Įquipped with a laptop PC go and simply connect the PC to the car with the USB cable on the ODB plug located below the steering wheel. Analyze the sensors of the car: Nissan DataScan A high CO rate may come from an oxygen sensor fault or from a decat car … I decided to investigate the o2 sensor following some smart advices. One can see the 2 sensors on the above picture : the one that is difficult to access is in red the easy one is in orange.īringing the car through technical inspection (French MoT), it appeared that the CO rate was too high and that the lambda value was bad: the CO was 2.25% instead of 0.3%, these measurements were performed at idle and at a very low RPM. I’ll do another article for the other sensor.
I will explain how to check if the 2 oxygen sensors in a R34 GTR (also valid for a R33 GTR) are dead and how to replace the one that is easy to reach. The O2 sensors of R33 and R34 GTR are the same but the R32 one’s are different. Consult port doesnt get power on ACC.How to diagnose a faulty oxygen sensor on a Nissan R34 GTR and how to replace it.Īfter chatting with a member of I decided to make a small update.īefore starting and to avoid confusion, there are 2 oxygen sensors on a R32/R33R34 GTR. Ensure car is either ON (ignition on, but not running) or RUNNING.
Plug other end into laptop usb or serial port (or for Pocket PC, into null-modem adaptor or blaZt iPAQ cable).The steps for actually using the cable and software (see next section) are relatively simple: Generally all Nissan Consult interface cables should work with all Consult software, although some circuit designs offer better compatibility with all vehicles. The cables are not 'straight through', but have an electrical circuit inside the connector (not just a case of putting connectors on the ends of a cable). Also some late model cars from 1999 may have an OBDII port and a Consult port, but only retain the consult port it for ancilliary systems (like AT, AirCon, HICAS, etc) diagnostics, but the main ECU may be OBDII.Ī 'consult interface' cable allows the connection of a Laptop/PC to a Consult capable car for diagnostics with Consult programs.
Consult is only supported on the Nissan ECUs, so replacement ECUs like the PowerFC, etc, will not support it (remapped/daughterboards ECUs or those with piggybacks like SAFC should be fine). There are exceptions to the rule, however.
If the car has the female consult port, it will most likely support consult. Nissan Consult is supported on most petrol powered (generally not diesel) Nissans built in the 1990s. These cars are usually built from year 1989 to 2000, including models such as 300ZX, Z32, Maxima, 240SX, S13, S14, Skyline, SR20DE, SR20DET, RB20, Altima, and Fairlady. Nissan cars that have the grey 14pin Consult connector (you'll usually find it near the fusebox).
