Phil's right. 1989 240 is LH 2.4 w/OBD(I) and will likely set a Check Engine for a missing EGR valve and solenoid.

Referring to Bill Garland's ECU table, some LH 2.4 ECU's were listed as for EGR or non-EGR, some it didn't seem to matter.

Referring in the FAQ here to the OBD codes from the ECU on port 2, for LH 2.4 none are listed for an EGR problem, so likely no CEL from it. However the EZK ignition controllers can set a number EGR related codes on port 6 that may set the CEL. Idling issues are noted. I'm not sure what would be involved for disabling it and jumpering at the connector without throwing a code, probably a resistor.
