Common Symptoms
- Reduced power mode
- Throttle response limited
- Engine power limited to partial throttle
- Throttle warning light on
- Check engine light on
Probable Causes (Ranked by Likelihood)
- TPS F signal wire shorted to ground Very High
- Faulty TPS F sensor inside throttle body High
- Corroded throttle body connector Moderate
- Damaged wiring near throttle body or engine Moderate
- Missing reference voltage to throttle body Low
Step-by-Step Diagnostic Procedure
-
Check TPS F voltage -- should not be near 0V; normal rest voltage depends on manufacturer
-
Disconnect throttle body and check F signal wire for shorts to ground
-
Inspect throttle body connector for corrosion from engine heat and moisture
-
Verify 5V reference and ground are present at throttle body connector
-
Replace electronic throttle body if TPS F is shorted internally
Frequently Asked Questions
Can I drive with code P2132?
Only short distances to a repair shop. The vehicle will have limited power. The PCM restricts throttle opening when it detects a low signal from the F track TPS since it cannot fully verify throttle position.
Is TPS F the same sensor as TPS 1 or TPS 2?
Different manufacturers use different naming conventions. TPS F is typically the secondary throttle body position sensor, which may also be referred to as TPS 2 or TP sensor 2. Check your vehicle's wiring diagram for the specific circuit assignment.
Can I replace just the TPS sensor?
On electronic throttle bodies, the TPS sensors are integrated into the assembly and cannot be replaced individually. The entire electronic throttle body must be replaced. On some older vehicles with separate TPS sensors, individual replacement may be possible.
