I need to test and potentially replace the CHTS. I see the lead to the sensor has a 2 inch long red "torpedo" looking device between 2 black connectors. It looks original as the 2 connectors are solid black with VW stamped on them. Anyone know what the red torpedo is and how the 2 black connectors come apart???

It's a resistor. I forget the value, Brad Anders' D-jet webpage will have the number. (240 ohms??) http://members.rennlist.com/pbanders
The plugs just pull apart. The sender wire and connector unplugs from the plastic housing on the resistor, and the resistor unplugs from the plastic housing on the wiring harness. --DD |

If yours is a stock 73 2.0 EFI, then you'll need the resistor in line with the -017 CHT. Otherwise 74-76 2.0s use the -012 CHT with no resistor, which are still readily available from many P-car/914 parts sources. Rich at HPH may still have one of each NOS for the 73 2L. |
