Here we\u2019ve got a Chevrolet Aveo 2010 with abnormal acceleration, and we\u2019re going to show you how to use Launch X431 PROS<\/a> V4.0 to diagnose where the problem is.<\/p>\n

Here we can see it presents acceleration around 1400rpm which will consume a lot of fuel.<\/p>\n

So turn on the device,
\nManually select the vehicle type and go to ECM diagnostic menu.
\nSelect \u201cRead fault codes\u201d.
\nThen we\u2019ve got the DTC: Voltage below the throttle position sensor circuit.<\/p>\n

Here we can take a capture to save the code.
\nBack to ECM menu, select
\nRead data stream>>Engine data
\nThere are 40 parameters, and we select
\nData about the throttle and the engine.<\/p>\n

Here we can see the control air relent is 34, which means it\u2019s correct.
\nBut throttle position sensor is at 2.75% and 0.14v, and 1400rpm, so
\nWe have a throttle position problem.<\/p>\n

So we check TPS graph,
\nAnd we try to reconnect the connector to
\nVerify it is tightened and adjusted well.
\nAs the TPS value is intermittent, we\u2019ll replace a new TPS.<\/p>\n

After we finish the throttle part, enter X431 PROS V4.0 the scanner.
\nSelect \u201cDiagnostic history\u201d and the record we just saved.
\nHit \u201cRapid Access\u201d to return to ECM diagnostic menu.<\/p>\n

Then we read fault codes again.
\nThere is no fault code, so we take a capture and go back.<\/p>\n

Read engine data stream again.
\nCheck selections about the throttle and confirm.
\nThen we\u2019ve got desired engine speed \u2013 840rpm, and it\u2019s oscillating.
\nAlso we\u2019ve got well-working oxygen sensor.<\/p>\n

Complete!
\nThis is how we use X-431 PROS V4.0 to diagnose acceleration for Chevrolet Aveo 2010.<\/p>\n
