Hi Bill,

Not yet. I found my 1991 240 has corrosion at ground collection that use a screw or bolt to secure to the plate or sheet metal. I did this service like in 2012 on all three 240s and all ran much better with better throttle response and improved fuel economy.

The (Penn?) Sylvannia silver star 9004 / HB1 I got like three years before were bright at first, yet have dimmed. A twist, use oil squirt, and tighten does the job. I also have ground straps between the unibody and exhaust at hanger unions.

The CPS cable does not connect to ground on 740 with EZK116. There is a cable shield sheath from the sensor end to the cable connector. I'm not sure right now, tho. The CPS connector end has three pins. Also, the distance between the sensor and the ideal center point may need some file use on Bougicord. Maybe it is better. Never had to before when replaced in 2009 on 1991 or 1990.

Auld, flea-infested owld brain cells. May have had too much ayyyyyyyg naaaawg. Makes up well with a giant glass of the strongly brewed earl grey tea. Earl grey tea and Eggnog! Helps with the type II Wilford Brimley's diabeetus.

You can test for continuity of ohms resistance and wiggle the cabel to see if there is a break in a conductor therein. I'll guess you tested that already.

I doubt there is something generating RF powerful enough in your 900. A gauss field meter, I guess it is called? The bulk head plate steel does some farrady cage match electrical engineering action between the engine bay and the under the dash stuff, I guess. There exist two maker of the CPS cable. Bougicord and another. If any damage like the oft described outsheath failure, exposing a light colorful and iridescent foil. If anything makes RF noise it is the alternator, HVAC blower, and I dunno. It'd take a lot of noise to interfere with signal or low volt DC carried in stranded copper alloy conductor used in the wiring harness.

At FCP Euro, much closer to you then iPd and also 10$ cheaper (copy and paste URL):

So the other some say is okay is Made in Duetchland by Bremi for 31$:

Has two spinning slips so the cable does not flop in teh breeze for 40 years!

I get these used at yunkyards and so have a collection of known goods CPS's in the truck and on a shelf should I ever have a garage again.

Spare ECUs or newer versions of ECUs your model can use helps as well as spare relays. I have a half dozen white fuel injection and other relays, merely reflow the solder, and add moar solder so welds do not crack again!

Easy to replace in the 700/900 engine bar! Sort of terrible in the 240 engine bay. The factory shop manual says 'pull the gear box' to replace this thing on 240.

Ha!
