Help needed with tec2 oxygen sensor


Hybrid240z

Recommended Posts

Can't find a replacement for the Bosch 48617B0 universal oxygen sensor that came with my tec2. The new universal Bosch numbers are different. The old sensor was manufactured in 2002. What is the correct Bosch sensor to use on the tec2? The auto parts store guy said it may be the 15730. Thanks.

I was just reading through the manual and these are the part #'s:

Heated Exhaust Gas Oxygen Sensor (HEGO)

The EGO sensor is essential for doing closed loop feedback

fuel control as found on all late model street vehicles. It is the key

sensor for producing good power with least emissions. It further can

be used to aid in calibration of both street and off-road vehicles. Several

styles exist but only two basic types are commonly used. The

simplest is the unheated single wire EGO sensor (GM P/N 8990741).

The single wire can be used only if the EGO sensor is mounted in the

exhaust manifold or within 10 inches of the manifold. If the EGO is

mounted farther away or after a turbocharger a heated sensor should

be used. PAF and PAFZ systems require a heated sensor.

 

EGO Sensor (Unheated)

The unheated, 1 wire oxygen sensor is the easiest to use since

all it requires is installing an M18-1.5 (sparkplug thread) boss in the exhaust. Use an M18-1.5 nut or an

EGO sensor weld-in adapter available from Electromotive. Mount the sensor boss in an accessible spot

close to the outlet of the exhaust manifold. Do not mount it more than 10 inches down from the exhaust

manifold. If a good welder is not available it may be possible to obtain an exhaust manifold or tubular

header equipped with an EGO fitting. Install the one wire EGO with anti-seize compound, being careful not

to get any of it on the sensor element, and run the wire up to the TEC terminal marked “EGOâ€.

Thanks for the info guys. JSM, I did see that info on the manual but that number is for the non-heated sensor. I'm planning on using a heated sensor. I did notice on the electromotive forum that you can run the analog output from the AEM wideband to the tec2 using a small circuit. I'm going to give that a try.

Sweet. I saw that today too! Make me one!
