Tachometer Does Not Indicate Correct Engine RPM
- Locate Data Link Connector (DLC) in engine compartment on left strut tower. Connect an external tachometer to DLC connector terminal No. 19 (Black wire). Start engine. If correct RPM is not indicated, check for open in Black wire between DLC and igniter. If okay, replace igniter (located under distributor cap on 1.6L engine or mounted to left strut tower near air cleaner on 1.8L engine).
- If correct RPM is indicated, check for open in Black wire between instrument cluster White 16-pin connector terminal No. 11 and splice. Check instrument cluster printed circuit for bad connections and cracks. If wiring and printed circuit are okay, replace tachometer.
