Hi Pplneedmusic,

You do own a Bentley, Haynes, or a Volvo OEM green factory service manual for your Volvo 240?

You can run down my message index. I've posted so many times with the same issues you experience. Why a Volvo 240 FAQ would be useful.

Bosch LH-Jetronic (fuel) version 2.4 and 3.1 (Socket 2 on OBD box) error code 1-1-3 (activates check engine light) lists an error in one or more of the fuel injectors. You may have a problem with corrosion in the brown fuel injector grounding wires or at the fuel injection connectors (corrosion, certainly if you reside in salty sea air or salty winter roads).

A Volvo TSB (technical service bulletin) lists removal of the fuel injector ground wire ring terminals that secure to the air intake port and then securing a new set of ring terminal using solder. Two sets of two ground wires, in brown insulation in a sheath, connect each to the air intake port runner. Loosening and tightening the bolts helps. The ground point (where the terminal secure) are on the top of the #2 and #3 intake port runner.

You may want top perform an inspection of the wire harness specific to fuel and ignition. Check the 25 ampere fuel injection fuse and fuse holder on the inner fender behind the battery. You may want to track down grounds, loosen and tighten the hardware, or fully remove, clean, and resecure the grounding wires and securing hardware using NoOX or DeOxit.

Bosch LH-Jetronic (fuel) version 2.4 and 3.1 (Socket 2 on OBD box) error code 2-3-2 (no check engine light)is lean or rich at idle. Repairing the cause(s) for LH-Jetronic fault code 1-1-3 may likely, yet may not correct fault 2-3-2.

Have you check the Bosch EZK (ignition and EGR control - Socket 6 on OBD box) for error codes? If you find faults in one (Jetronic fuel or EZK ignition), always check the other system (Jetronic fuel or EZK ignition) for error codes. Always. Than remedy the fault.

The Bosch LH-Jetronic and EZK systems are extremely integrated. So always check for faults in both systems.

Questions?
