Hi AG,

Here's a quote from 1989-1993 240 fault tracing manual for LH 2.4 EZ116K TP 32394/1

Checking the RPM sensor connector
- Take apart the RPM sensor connector
- Carefully scrape away dirt and deposits in the connector and clean the terminals
- Grease the connector. Use P/N 1161417

OBD code 2-1-4 check for contact resistance

They specify in another section the same story for the injector EFI connectors
- Disconnect battery minus cable
- Apply rust removal spray 1161034-2 to exposed contacts
- blow with compressed air
-Squeeze grease 1161417-9 into female contacts directly from the tube
- Using a spare male pin check that female contacts give a good contact and remain in place when the male pin is pulled lightly.

Resistive contacts will set a 2-1-4 code

I think that Volvo's "rust remover" is some contact cleaner, Spook?
Dunno what grease that is but Volvo Penta sells it at Ebay... more pricey
than Penetrox-A.

DeOxit has a new anti corrosion grease that they were giving free samples, check their website

Read this about Penetrox-A: http://sw-em.com/anti_corrosive_paste.htm

Good luck, Bill
