P0136 Chrysler Code - Heated Oxygen Sensor Circuit Malfunction Bank 1 Sensor 2
Quick Answer
The Heated Oxygen Sensor 2 (HO2S2) (Downstream), after the three-way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. Common causes include Exhaust gas leaks, Faulty Heated Oxygen Sensor 2 (HO2S2) (Downstream) Bank 1, Heated Oxygen Sensor 2 Bank 1 harness is open or shorted. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Frequently Asked Questions about P0136 Chrysler Code
What does the OBDII code P0136 mean for a Chrysler?
P0136 indicates a malfunction in the heated oxygen sensor (O2 sensor) circuit for Bank 1 Sensor 2, which monitors the efficiency of the catalytic converter behind the engine on Bank 1.
What are the common symptoms of code P0136 in a Chrysler?
Common symptoms include the check engine light turning on, reduced fuel efficiency, failed emissions tests, and, in some cases, rough idling or poor engine performance.
What causes code P0136 to appear in a Chrysler?
Common causes include a faulty Bank 1 Sensor 2 oxygen sensor, damaged wiring or connectors in the sensor circuit, exhaust leaks, or issues with the vehicle's powertrain control module (PCM).
Can I drive my Chrysler with a P0136 code?
While the vehicle may still run, driving with a P0136 code is not recommended as it can lead to poor fuel economy, increased emissions, and potential damage to the catalytic converter if not addressed.
How do I diagnose code P0136 on a Chrysler?
Diagnosis involves checking the oxygen sensor and its wiring for damage, testing the sensor's voltage output, inspecting for exhaust leaks, and using a scan tool to monitor live data from the sensor.
How do I fix code P0136 on a Chrysler?
Repairs may include replacing the faulty oxygen sensor, repairing or replacing damaged wiring, fixing exhaust leaks, or, in rare cases, reprogramming or replacing the PCM.
How much does it cost to repair code P0136 on a Chrysler?
The repair cost depends on the issue, with oxygen sensor replacement typically costing $150–$300, including parts and labor. Wiring repairs or PCM replacement may be more expensive.
What tools are needed to troubleshoot P0136 on a Chrysler?
Tools include an OBDII scanner, a multimeter to test sensor circuits, and basic hand tools for removing and replacing the oxygen sensor.
Is P0136 a common issue in Chrysler vehicles?
While not overly common, P0136 can occur in Chrysler vehicles due to aging oxygen sensors or wiring wear, especially in older models or high-mileage vehicles.
Can a bad catalytic converter cause code P0136?
Yes, a failing catalytic converter can sometimes trigger P0136 if it affects the readings from the downstream oxygen sensor (Bank 1 Sensor 2).
