2-1/16" OIL PRESSURE, 5-100 PSI, COBALT DIGITAL

Hi Patch, thank you for contacting us. E0 would indicate a sender error. This could be caused by a sender issue, but more commonly it's caused by an insufficient sender ground. That sender must create a ground connection through the threads and an excessive amount of thread sealant can prevent that ground, causing the E0 error. If you have access to an ohmmeter or multimeter to measure resistance, you can also check the sender's resistance. Make sure to disconnect the gauge from the sender before testing, but the sender should read approximately 250 ohms without the engine running.

Hi Jake, thank you for the question. While we have no information on your 1988 Landcruiser and what the sender resistance would be, it's extremely unlikely that our gauge would match up to it. The 6927 Oil Pressure uses a resistance based sender that has a general range of 250 ohms at 0 psi and 40 ohms at 100 psi.

Thank you so much for contacting us. While we don't sell these gauges without their sending units, we do service everything that we sell, and for considerably less than what a typical replacement would cost. I would strongly recommend sending the gauge itself into our shop for inspection. You can use this form: http://www.autometer.com/media/Service_Form.pdf There is never any charge for diagnostic work and we'll contact you prior to performing any work that would cost you money. Hope this helps!

Hi Izzy, thank you so much for contacting us. The sending unit included with this gauge is the only one that it is compatible with. In instances where you've got a tight fit, we typically remote mount the sending unit with a small length of braided line. If it's an issue of clearing a distributor, you can often times use an angled pipe fitting and/or an 1/8" NPT extension as well. Hope this helps!
