Common Symptoms
- Check Engine Light illuminated
- Reduced engine power mode
- Inconsistent throttle pedal response
- Engine hesitation or surging
- Idle speed fluctuations
Probable Causes (Ranked by Likelihood)
- Faulty throttle position sensor E High
- Corroded or damaged connector at TPS E High
- Open or short circuit in TPS E wiring Medium
- PCM/ECM internal circuit issue Low
- Incompatible or incorrect TPS installed after repair Medium
Step-by-Step Diagnostic Procedure
-
Scan for codes and record freeze frame data for P2137
-
Monitor TPS E voltage with scan tool - should read 0.5-4.5V and change smoothly with throttle input
-
Check 5V reference and ground circuits at the TPS E connector
-
Inspect wiring between TPS E and PCM for damage, chafing, or corrosion
-
Verify correct TPS part number for the application if recently replaced
Frequently Asked Questions
What does P2137 mean?
P2137 indicates a general malfunction in the throttle position sensor E circuit. This is a redundant throttle position sensor used in some vehicles as an additional safety check for the electronic throttle control system.
Can I drive with P2137?
You can drive short distances but expect reduced power and inconsistent throttle response. The vehicle should be diagnosed promptly as electronic throttle issues can worsen.
Why do some vehicles have a TPS E sensor?
Some manufacturers use multiple redundant throttle position sensors (A through E or more) as a safety feature. If one sensor disagrees with the others, the PCM can detect the fault and protect the driver.
How much does it cost to fix P2137?
Repairs typically cost $200 to $500. European vehicles with integrated throttle bodies may cost more ($400-$700) due to higher part costs.
