2002 VW Polo P1173 Fault Code: How to Fix Throttle Body Issue Without Going to Garage
Hi everyone, I recently encountered fault code P1173 on my 2002 Volkswagen Polo. The code indicates a 'Throttle Actuation Potentiometer Signal 2 Signal Too High' issue. I'm looking for cost-effective DIY solutions before visiting a garage. Has anyone successfully resolved this problem themselves? What steps did you take? Thanks in advance for any advice or tips.
Hello! For P1173 on your 2002 VW Polo, the issue is typically related to the throttle body sensor signal being too high. Before replacing the throttle body (which can be expensive), check live data readings using an OBD2 scanner to confirm the fault. Ensure the wiring harness and connectors are in good condition, as damaged wiring can cause false signals or intermittent faults. If you decide to replace the throttle body, consider looking for a used one with at least a 1-month or 4-week warranty to ensure reliability. Always check current market prices before purchasing.
