B26A2 Peugeot 405 OBD Code

OBD/2 B26A2 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.

In most cases, the TCM is integrated into a single housing with the PCM. Nevertheless, the section of the module which controls (automatic) transmission function may be powered up separately. In any case, the TCM is typically powered using switched (only present with the ignition switch in the ON, start, or run position) voltage. This circuit is normally equipped with a fuse, fusible link, and/or a relay. Frequently, the PCM and TCM are powered using the same relay albeit by separate circuits. Access to a reliable vehicle information source will yield necessary details of the TCM power circuit for the specific vehicle in question.

B26A2 Peugeot 405 Error Code Repair Process :

If your vehicle failed a B26A2 test and the B26A2 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 o2 sensor circuit low voltage (bank 1 sensor 2) 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 o2 sensor circuit low voltage (bank 1 sensor 2): 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 Peugeot 405 B26A2 OBD2 Code

A common cause of code B26A2 is the failure of O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2), but there are several other possible causes as well, such as ;

Camshaft Position Sensor harness is open or shorted
Camshaft Position Sensor harness is open or shorted
Faulty Mass Air Flow (MAF) sensor
Three way catalyst converter Bank 1
