Trouble Codes

Fault codes P0171 and P0174 The codes mentioned in the title point to two different types of faults P0171 – for a poor fuel-air mixture feeding the cylinder block No. 1 P0174 – for a poor fuel-air mixture feeding the cylinder block No. 2. Both codes inform that the mixture feeding cylinder block no. 1 … Dowiedz się więcej

DTC P1238: High voltage turbocharger boost control solenoid valve voltage Possible reasons for the error code p1238 Most often turbine contaminated with soot Break in the control line of the boost valve Damaged turbo-cylinder valve or turbocharger boost control solenoid valve Leakage in the vacuum of the turbocharger supercharger solenoid Effects: power drop, problems with … Dowiedz się więcej

DTC P1237: Positive deviation of the boost control Possible reasons for the error code p1237 Most often turbine contaminated with soot Damaged turbo-cylinder valve or turbocharger boost control solenoid valve Leakage in the vacuum of the turbocharger supercharger solenoid Effects: power drop, problems with high turnover

DTC P1236: Negative deviation of the boost control (in practice – turbine contaminated with soot.) Defect Vacuum control of the turbocharger boost regulation Pierburg can not move the turbine VTG blades), (effects: power drop, problems with high revolutions) Permanent generation P1236 – changed Pierburg valve plugs. Faulty fuel pump module assembly Open or short circuit … Dowiedz się więcej

DTC P1331: Low reliable dynamics of correlation of CKP-CMP sensors malfunction, more often the deflection of the main shaft / knock position sensor effects: sudden engine run out (also while driving), impossible to run on warm or problems with running hot / hot – on cold piles normally Possible reasons Low fuel level or fuel … Dowiedz się więcej

Circuit / system description trouble code p1101 The engine control module (ECM) compares the actual air flow based on the throttle position with the calculated air flow based on the absolute intake manifold (MAP) and mass air flow (MAF) sensor readings. The ECM detects that the actual air flow rate is greater than the calculated … Dowiedz się więcej

OBD2 error P0141 possible causes The reasons that may lead to the establishment of code P0141 may be the following: Defective oxygen sensor (lambda sensor) Bank 1 sensor 2 Burnt heater fuse for the second lambda probe or shorted to ground Poor electrical connection in the connector of the second lambda sensor Defective motor control … Dowiedz się więcej

Diagnostic Fault Code P0420 Low performance of the catalyst system Check for the following conditions that may cause a decrease in catalyst performance: • Ignition interruption • High consumption of engine oil or coolant • Delayed timing phases • Poor or small spark • Poor fuel mixture • A rich fuel mix • Defective lambda … Dowiedz się więcej

Diagnostic Fault Code P0172 Learn the state of the mixture rich in the fuel mixture control system Possible causes P0172 Flexible, looped or incorrectly connected flexible vacuum lines Pressed or obstructed air intake duct Air filter is dirty or blocked Blocking the throttle body with foreign objects The amount of fuel in the crankcase due … Dowiedz się więcej
