Thanks for info Frank. The new sensor is a Bosch 13913. The coax cable is
fine. Pulled back the rubber boot on end and it looks like the day it left the
factory. Outside wires safe distance from spade connector. Checked continuity
to ECU as per Bentley and all checks out. Continuity to ground and nothing
when connected to sensor. Made a good splice to sensor but had to extend the
wires using regular but large enough automotive wiring. Does the sensor
require special wire?
Maybe I will have to address exhaust leak even though I don't think the
small leak that I have would impact performance of the sensor that drastically.
Gas mileage not all that bad as I'm getting 19 to 20 miles per U.S. gallon
even while driving 120 km per hour. Not bad for a regular Vanagon fully loaded
for a week of camping. I'm not driving a regular Vanagon.
I would still like to fix this sensor issue. Could it be a faulty OXY sensor?
Getting 12 volts at OXY heater wiring with engine running. Doesn't matter
which white wire goes to the brown and red/yellow wires? Would it even matter
if the heater is connected?
Gerry, the exhaust can have no leaks upstream ! The wire you used to make
the extension is not critical as far as I know. The heater wires are not side
sensitive and do not have anything to do with the info sent to the ECU.
Could be a faulty OXY sensor, but you can check this with a good ohm meter.
Reading should be + - .5 volts when engine is running. Check your Bentley for
exact testing values. I have one of Ken Lewis' OXY sensor readers permanently
installed on my dash and another in the shop i use to test suspect OXY
sensors.
Are you going to LiMBO's West River Westys, Townsend, VT., July 10 ~ 13
? Rita & I will be there, leaving here Thursday morning. I could bring my
OXY sensor tester if you want.
