'92 240: codes 1-3-1 & 1-3-2??

[Bill Stehlin]

Car running fine. Filled up w/ 11 gal. gas and when started "check
engine" light came on and stayed on. Car appears to run OK. Checked
for codes and got 2-3-2 and 1-3-1 in that order. Couldn't find info
in Bentley for meaning of these codes when check engine light remains
on. Any idea what's indicated?
Thanks.

Hi Bill,

I got this from;

http://www.brickboard.com/FAQ/700-900/EngineOBDCodes.htm

These are for the Bosch LH2.4 Fuel Injection System, so I hope it's of some
value to you and your 240.

Code 2-3-2 = Fuel trim (Lambda control) too lean or too rich at idle.
If too rich: high fuel press., leaking injector.
Symptoms - Idling problems.

Code 1-3-1= Ignition System RPM signal missing on starting. Wiring Fault or
RPM sensor bad.
Symptoms - Engine will not
start................(Obviously this does not add up in your case.)

Good Luck.
