OBD2 Codes: Diagnostic Trouble Codes List

OBD2 Code: P1670 Injection Pump System Malfunction

When the ignition switch was turned ON, or when the ECM determines whether it is an error of RAM in ECM or not, the ECM conducts a single communication. If any one of the following status occurs in the communication, the ECM conducts one more communication. While the ECM is conducting the communication, if (a) is duplicated 20 times continuously, or if (b) is duplicated 20 times continuously, or if (c) is duplicated 2 times continuously, the ECM outputs the OBD2 code P1670.

1. There was a communication error when receiving data.
2. Data sent from the injection pump correction unit does not match to the data received from the ECM.
3. Data received from the pump ROM is not input in the period of 1024 msecond.

Although the determining process is completed without a problem, the ECM conducts the communication again if an undefined code is found while checking an identification code of the receiving data. If the undefined code was duplicated 20 times in a row, the ECM outputs the DTC.

SAP P2442 Toyota Landcruiser and Prado

The secondary air intake system is part of a vehicle’s emissions control system and can sometimes trigger OBD2 code P0420. It works to support the function of the catalytic converter. The switching valves allow the air pump to pump air into the exhaust stream when an engine is cold, speeding up the process of warming the catalytic converter to burn unused fuel. We have permanent solution for the catalytic and the air injection pump for vehicles having dual exhaust. Diagnostic trouble codes P2442 and P2440 along with P0420 fix is available.

B2AA0-92 CTBA City Brake Active System

Commonly known as brake orders are issued too often, this error is caused when the collision mitigation system or cross traffic monitoring cameras / radars assess a possible collision. It is very common in Pakistan as we have multiple types of fast approaching vehicles at intersections. The system can reset on its own, if not calibrations maybe required. It is also called cross traffic braking assist at some places

OBD2 Code: B12C5 Honda Smart key

Possible failure area is Engine Start / Stop button, however low smart key battery or a bad Key decoder (antenna) can also cause this error. The smart key module is hidden behind the odometer

OBD2 Code: P0420 Toyota Prius

As the P0420 code states, whenever the catalytic has choked to a stage that the vehicle performance is greatly compromised this code will set in. The catalytic is cleaned and re-installed. Sometimes this code of P0420 also sets in if the oxygen sensors on the cat-con have stopped functioning. We also provide permanent delete function of this OBD2 code P0420.

P2788 Honda Vezel and Honda Fit

Transmission adaptive learning code, please do not ignore this code as this can lead to permanent failure of your dry clutch or dual clutch transmission. Replenish the fluid with Honda DW1 ATF not CVT. We have recovered many cars that had been poured with wrong oil which may cause permanent damage to an expensive gearbox. Re-calibration is always recommended whenever new oil is poured.

C1391 C1201 Prius ABS Fault Abnormal Leak in Accumulator

Toyota Prius 2010 vehicles had a factory defect that caused leakage of nitrogen from the pressure system effecting the braking of the vehicle. We upgrade the ABS units with a 2013 model in case the following errors are seen. Please note that ABS unit needs to be calibrated very precisely. We also recommend to replenish the brake fluid on time to keep the ABS unit healthy.

OBD2 Code P0300 P0301 Honda and Toyota Cylinder Misfire

P0300 is OBD2 trouble code for Random/Multiple Cylinder Detected. P0301 shows that Cylinder number 1 experiencing misfire. A popular error on Honda vehicles that may show up if the coil packs of your car are at an end. Replace the bad coils or the complete set and check with an ohm meter before installation. P0351 is code for no 1 coil circuit malfunction.

P0A7F HV Battery Capacity Serious Deterioration

This DTC error will come up if the traction battery of your Honda Civic or Insight has completed its life cycle. It is recommended to change the pack ASAP to protect other electronics that may heat up and cause further deterioration of expensive controllers.

C1259 HV Control System Regenerative Malfunction

C1242 Open Circuit in IG1/IG2

If there is a problem with the master cylinder solenoid (skid control ECU) and its power supply circuit. The skid controls ECU stores the diagnostic trouble codes and brings vehicle operation under the fail-safe condition. If the voltage supplied to terminal IG2 is not within the DTC detection range due to malfunctions in parts such as the battery and generator circuit, this OBD2 codes will be present. In Simple terms always check the standard 12V battery condition and measure the voltages when the car is ON and when OFF to ascertain whether it is getting charged or not and them move on to the ABS unit.

P3190 Poor Engine Power

From the HV ECU, the ECM receives data such as power output required for the engine (required output), estimated torque produced by the engine (estimated torque), engine RPM of control target (target RPM), whether the engine is in start mode or not. Then, based on the required output and target RPM, the ECM calculates a target torque that is to be produced by the engine and compares it with the estimated torque. If the estimated torque is very low compared with the target torque, or the engine start mode continues for the specific duration calculated by water temperature, an abnormal condition is detected.

Diagnostic Trouble Code: P0A80 Toyota Prius Hybrid Battery

When a OBD2 code P0A80 is read / stored in system, it means that the ECM has detected a malfunction in the hybrid vehicle battery management system (HVBMS). This code indicates that a cell has gone weak in the hybrid battery pack. Hybrid vehicles (which do not require external charging) utilize nickel metal-hydride battery packs. Battery packs are actually blocks of batteries (modules) that are wired together using sections of connectors or cables. The typical HV battery is composed of eight (1.2-volt) cells in series. Twenty-eight modules make up the typical HV battery pack.
The voltages are from 205VDC to 236VDC between the inverter and the power extractors, safety measures must be taken to avoid permanent damage or injury to the persons performing work on HV car.

OBD2 Code P0420 Catalyst System Efficiency Below Threshold

The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream O2 sensor reading should be fairly steady. Typically the OBD2 code P0420 triggers the Check Engine Light if the readings of the two sensors are similar. Oxygen sensors are also referred to as O2 sensors.

C1406 2010 Toyota Fj Cruiser Description

The speed sensor detects the wheel speed and sends the appropriate signals to the Skid Control ECU. These signals are used for brake control. The speed sensor rotors have rows of alternating N and S magnetic poles and their magnetic fields change when the rotors turn. Each speed sensor detects that magnetic change and sends a pulse signal to the Skid Control ECU.

Ford Ranger Wild Track Adblue Off

Ford Ranger Wild track P204F is a Euro6 Compliant vehicle. It comes equipped with an Adblue SCR system. The system P1575-A1 is famous for causing reliability problems. Some times the car gets into a No-start position and the only option is to repair or replace the necessary components. The engine is a famous Duratorq Turbo Diesel. We deleted the Adblue fluid monitoring system from its computer and permanently resolved the issue.

P2583 CTBA Radar Aiming

P2583 Millimeter Wave Radar is a DTC related to driving support system Radar malfunction, It can also cause malfunction in adaptive cruise as well as early haptic feedback on the RFP pedal. Contact our teams for a complete solution to the CTBA system. We also do cruise limit unlock (110km limit unlock) on Honda Hybrids
