C1818 Oldsmobile F-85 OBD Code

OBD/2 C1818 error code description and symptoms.

Engine Coolant Temperature (ECT) Circuit High Input Indicates the sensor signal is greater than Self-Test maximum. The ECT sensor maximum is 4.6 volts or -50 C (-58 F). Note on some vehicles that are not equipped with an ECT sensor, CHT can be used and can set this DTC. Open circuit in harness Sensor signal short to power Damaged PCM Improper harness connection Damaged sensor ECT V PID reading greater than 4.6 volts with key ON and engine OFF or during any engine operating mode indicates a hard fault.

Circuit High Input codes like C1818 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

Common Causes of Oldsmobile F-85 C1818 OBD2 Code

A common cause of code C1818 is the failure of C1818 Air Suspension LR Air Compress Request Exceeded Max Timing, but there are several other possible causes as well, such as ;

Engine Control Module (ECM)
Faulty starter motor
Faulty Variable Camshaft Timing (VCT) position solenoid
Oil flow restriction in the oil passages or the VCT valve body

C1818 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
