C2338 Daihatsu U4b OBD Code

OBD/2 C2338 error code description and symptoms.

EGR Flow Insufficient Detected The EGR system is monitored during steady state driving conditions while the EGR is commanded on.
The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum. Vacuum supply EGR valve stuck closed EGR valve leaks vacuum EGR flow path restricted EGRVR circuit shorted to PWR VREF open to D.P.F. EGR sensor D.P.F. EGR sensor downstream hose off or plugged EGRVR circuit open to PCM VPWR open to EGRVR solenoid D.P.F. EGR sensor hoses both off D.P.F. EGR sensor hoses reversed Damaged EGR orifice tube Damaged EGRVR solenoid Damaged PCM Perform KOER self-test and look for DTC C2338 as an indication of a hard fault.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code C2338, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code C2338 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

C2338 Daihatsu U4b Error Code Repair Process :

If your subsidiary throttle valve solenoid circuit malfunction check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system C2338 and engine control unit are in charge of monitoring a bunch of different subsidiary throttle valve solenoid circuit malfunction, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Daihatsu U4b C2338 OBD2 Code

A common cause of code C2338 is the failure of Subsidiary Throttle Valve Solenoid Circuit Malfunction, but there are several other possible causes as well, such as ;

Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Faulty select solenoid
Faulty Variable Camshaft Timing (VCT) position solenoid
Open circuits caused by corrosion of electrical connectors.

C2338 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.
