C1588 Citroen 2cv OBD Code

OBD/2 C1588 error code description and symptoms.

Output Shaft Speed sensor circuit intermittent failure The output shaft speed sensor signal to the PCM is irregular or interrupted.
Harness connector not properly seated Harness intermittently shorted, or open Harness connector damaged OSS sensor damaged, or not installed properly Verify harness and connector integrity Verify OSS sensor proper installation.

As the engine heats up and combustion becomes easier and more complete, the PCM will command the idling control valve to increase the amount of air entering the engine to suit the changing conditions. However, when the load on the engine changes, say, when some electrical consumers or other systems are either turned on or off, the PCM adapts the signal voltage to the idle control valve to ensure that the idling speed remains stable, and at the RPM specified by the manufacturer.

C1588 Citroen 2cv Error Code Repair Process :

If your vehicle failed a C1588 test and the C1588 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses scp (j1850) invalid or missing data for interior environment a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look scp (j1850) invalid or missing data for interior environment: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Citroen 2cv C1588 OBD2 Code

A common cause of code C1588 is the failure of SCP (J1850) Invalid or Missing Data for Interior Environment, but there are several other possible causes as well, such as ;

Camshaft Position Sensor harness is open or shorted
Damaged camshaft position (CMP) sensor
Faulty Variable Camshaft Timing (VCT) position solenoid
Erratic camshaft position due to low oil pressure

C1588 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.
