Our certified mechanics come to you · Get a fair and transparent estimate upfront
P2137 is a diagnostic trouble code (DTC) for "A Camshaft Position Actuator Control Circuit Low Bank 2". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
P2137 is an OBD-II generic code for the engine control module (ECM) detecting the throttle pedal position sensors B and C voltages do not correlate to each other for return voltage to the ECM.
The ECM monitors the throttle position sensor (TPS) and has detected the B and C sensors signal return to the ECM do not correlate with each other.
One of the sensors has an internal fault.
The sensor circuit or connector has a loose or broken connection.
The Check Engine light will be illuminated and the code is set in ECM memory as a fault. The light will stay on unless the problem goes away for more than three running cycles.
The TPS has redundant sensors for the throttle position and may not have a drive complaint on some vehicles.
On some vehicles, the vehicle may go into limp home mode and limit the throttle opening and throttle response.
Scans for codes and documents the code in the ECM and looks at the freeze frame data for failure.
Checks the TPS wiring and connection for loose or corroded connectors.
Scans and views data from the TPS while operating throttle to see which sensor is failing or not correlating.
Follows the manufacturer pinpoint tests for the diagnosis and replacement of the TPS.
On some vehicles, the two TPS sensors B and C may be inside the same sensor and would be replaced as a single unit.
Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired
Failing to clear the ECM codes after the codes are fixed
Replacing the TPS without verifying the sensor has a problem
Code P2137 is a problem with the TPS and this can cause no throttle control problems and should be fixed immediately. The TPS is needed to control the throttle opening and closing.
Replace the TPS assembly if it is a single unit for both sensors or replace the failed sensor if they are two separate sensors.
Repair the connector pins of corrosion or loose connections at the TPS or the ECM.
Code P2137 is for a code that two TPS sensor signals do not agree with each other on throttle movement. Most vehicles will have a single sensor assembly that houses multiple sensors in one. It is replaced as an assembly.
